According to the purpose of the pallet, the pallet is generally divided into padding, single-layer turnover, stacking, shelf use, etc. Different load requirements for pallets under different conditions.
According to the basic requirements, the load requirements of the pallet are divided into static load, dynamic load, and shelf load.
The static load is the maximum load weight that the pallet can bear when the plastic pallet is placed on a flat surface and the goods are evenly laid on the pallet.
The dynamic load refers to the maximum load weight that can be withstood when the pallet is in a dynamic operation and the goods are evenly laid on the pallet when using equipment such as a forklift.
The shelf load refers to the maximum load weight that can be tolerated when the pallet is placed on the beam storage shelf or other heavy-duty storage shelves.
A single plastic pallet is the best choice if the forklift is a manual hydraulic forklift or a hybrid mechanical and manual hydraulic forklift.
If the forklift used is an electric and motorized forklift, both double-sided and single-sided pallets are available.
It's not smart to blindly compare the price of the product. Good raw materials and design can greatly extend the life of pallets.
If the plastic plastic is used on the three-dimensional warehouse shelf, the first step is to consider whether the structure of the pallet meets the shelf requirements.
Under normal conditions, the 4 way entry pallets (three runners back pallets) are better choices because the goods on the shelf can only be inserted from two directions.
As the structural foundation of a unit load, pallets support goods in a stable fashionand allow handling & storage efficiencies.
Here're the benefits of plastic pallets:
Durable. Plastic pallets are about 10 times longer than wooden pallets. In fact, steel pallets and plastic pallets are hard to distinguish in terms of life expectancy.
Reliable. It’s acid-resistant, alkali-resistant, corrosion-resistant, non-perishable.
Security. It’s nail-free, non-toxic, tasteless, non-combustible, no electrostatic sparks.
Lightweight. Plastic pallets are lighter than the same size wooden pallets, thus reducing the weight and cost of transport.
Health. Plastic pallets can be cleaned and reused, and the U.S. Department of Agriculture is promoting companies
to use plastic pallets to carry products.
Applicability. It’s not only suitable for stacking each other in warehouses and on a wide range of shelves, but also suitable for all types of truck transportation, convenient material series, unitized transportation.
Convenient for international trade. The plastic pallet is fumigation-free and can be used directly for export.
Irreplaceable. It’s irreplaceable in some industries such as food, beverage, pharmaceutical, and other industries.
Insurance. As a result of the damage resistance of plastic pallets, workers’ compensation claims were reduced accordingly. And the reduction in the use of wood in the factory is equal to the reduction in fire insurance premiums.
There are many types of plastic trays, why are nine-foot plastic pallets so popular now?
Structure
Different from double-sided plastic pallets, nestable plastic pallets can be used with a manual hydraulic car and can be entered on all sides.
Weight
Weight is an important factor affecting pallet prices. Nestable plastic pallet significant saving on materials at the bottom of the pallet.
Warehousing
It can be stacked and can save a lot of space when idle.
It is worth noting that nestable plastic pallets usually carry less than a double-sided pallet. Therefore, it is necessary to pay attention to whether the weighing capacity of the pallet meets the demand before purchasing.
Plan A -- not going to get back the pallets.
Plan B -- when you going to get back the plastic pallets after the shipment.
Tips: as we know, plastic pallets are fumigation-free and this advantage can save a lot of time and money in transit.
Tips: using a pallet can reduce the risk of damaging a product when moving it.
Tips:
The plastic pallets are much lighter than the wooden pallets. For airfreight shipping, the plastic pallets can help you save more money.
Tips:
* The plastic pallets are totally meet the strict requirements as stipulated by the FDA.
* The PP or HDPE plastics are chemically inert and won't contaminate drugs when they are left for a long time.
Tips:
Basically, the pharmaceutical and foodstuff plastic pallet share the same features.
Tips:
* Recessed rings ensure the drums don’t fall or slip during shipping.
* The 48″ x 48″ plastic pallets with recessed rings are popular for shipping and transporting drums.
Tips:
The spill control pallets are so important for volatile, hazardous, and corrosive chemicals which can cause injuries or damage the storage racks.
-Used as a floorboard, plastic pallets do not need to move after loading the goods. It only needs to be moisture-proof and waterproof. We can choose simple, low-cost plastic trays, such as nestable Industrial Pallets. And we should also pay attention to the static load of pallets.
-The structure of plastic pallets directly affects the efficiency of the use of plastic pallets. And the suitable structure can give full play to the characteristics of the high-efficiency operation of forklifts.
-It’s necessary to choose a high-strength plastic pallet for transportation, handling, loading, and unloading.
-For shelf use, we should consider whether the structure of the plastic pallets is suitable for stacking on the shelf.
-For the pile of stamping uses, a double-sided pallet is much better than a single-sided one. Single-sided plastic pallet only has one carrying surface which would cause damage to lower-level goods.
-It’s also necessary to consider the size of the transport vehicle, containers, and transport trucks.
PP and PE are both important raw materials for plastic pallets. So which one is better for pallets?
Also known as polypropylene, it is a semicrystalline thermoplastic.
It has high impact resistance, mechanical sub-strong, resistance to a variety of organic solvents, and acid-base corrosion.
Polypropylene is mainly used in the production of plastic pallets, plastic tables and chairs, plastic trash cans, plastic film, and so on.
The name is polyethylene, which is one of the most commonly used polymer materials in daily life. Polyethylene is resistant to a variety of organic solvents, resistant to a variety of acid-base corrosion, but not antioxidant acids, such as nitric acid.
It could be oxidized in an oxidizing environment.
Polyethylene is used in large quantities to make plastic trays, plastic trash cans, plastic tables and chairs, plastic bags, plastic film, and milk barrel products.
Physically, PP makes plastic trays that are more flexible than PE-made plastic trays and are impact-resistant.
PP is more resistant to high temperatures than PE and can be used at pasteurized temperatures.
There are two of the most common beam width dimensions of pallet shelves:
- 2300 mm wide shelves can be placed two pallets of 1200mm x 1000mm;
- 2700 mm wide shelves can be placed in three pallets of 1200mm×800mm.
The appropriate tray size should conform to the size of the transport to,
The appropriate pallet should be selected according to the packaging specifications of the pallet loaded goods:
There are three dimensions to reflect the load capacity: Static load, Dynamic load, Racking/shelf load.
Static Load
A static load is defined as a non-varying load; when weight is placed on an object that is kept at rest.
Dynamic Load
A dynamic load refers to the weight that is placed on an object and then put in motion.
Racking/Shelf Load
A racking load is the strength load rating for when a pallet is placed in a racked system.
1. Corner drop test
The purpose of this test is to determine the diagonal rigidity of the top deck of the pallet and its resistance to impact.
2. Static shear test
The purpose of this test is to simulate the approximate forces induced through lateral deck shear.
3. Bottom deck bending tests
The purpose of this test is to determine the strength and stiffness of the bottom deck between block or stingers when handling on twin rack conveyors or narrow span beam rack supports.
4. Stacking test
The purpose of this test is to determine the ability of the pallet top and bottom decks to withstand the local effects of widely varying payloads on sub spans of decks between blocks and stringers in a block-stacking situation.
5. Compression tests for blocks or stringers
The purpose of this test is to determine the compression stiffness and strength of the blocks or stringers of the pallet.
6. Fork lifting tests
The limiting condition of use for non-rackable and non-stackable single or double-deck pallets is the bending of the pallet on fork arm supports under the top deck of the pallet. With a forklift test, we can measure the bending strength and bending stiffness.
7. Static airbag bending test
The purpose of this form of bending test is to simulate, as near as practically feasible, certain load applications as commonly encountered in the field.
8. Static wing pallet bending test
The purpose of these tests is to determine the bending strength and the bending stiffness of winged pallets during lifting with slings.
9. Static bending test
The purpose of these tests is to determine the bending strength and the bending stiffness of the pallet in pallet in racking situations.

If the plastic pallet is used in accordance with the correct use specifications, in addition to being able to play its full role, it can also extend its service life, saving the purchase cost of plastic pallets.
Here is a basic introduction to the manufacturing processes commonly associated with plastic pallets, including rotational molding, injection molding, structural foam, compression molding, and profile extrusion.
An injection molder includes a heated barrel with a rotating screw. Virgin plastic and colorant are melted together in the barrel. The melted plastic is then injected into a mold that is clamped together, and pressure is applied. The injection and clamping forces are quite high.
Copolymer polypropylene or high-density polyethylene resin often is used for injection molded pallets. The cost of high-pressure injection molds is quite high, but the process has a fast cycle time. The high pressure also enables the manufacture of pallets or other products with detailed features.
Structural foam molding is a form of low-pressure injection molding. The mold cavity is injected with polyethylene or polypropylene plastic pellets and nitrogen gas. Heat activates the blowing agents, which in turn create a cellular core with a solid outer skin. This process requires less raw material and also creates plastic with a higher strength-to-weight ratio. The mold itself is less expensive than those for high-pressure injection molding.
The most common thermoformed pallet anyone is likely to see is a U.S. Postal Service pallet, but they are used in many supermarkets, too. Thermoforming is a two-step process. It begins with heating plastic pellets, typically polyethylene, to create an extruded plastic sheet of the desired thickness. Then, either one or two sheets are formed against molds as the air between the mold and the sheet is evacuated. Thermoforming molds are substantially cheaper than injection molds, but cycle times are slower.
A thermoformed plastic pallet is typically very lightweight and durable. Twin-sheet thermoforms pallets are hollow, which makes them susceptible to water retention if punctured and exposed to rain. Normally this is not an issue because they usually are kept undercover.
Compression molding is another tried and true method of making plastic pallets and molded pallets made of other materials, such as wood chips and resin. The two-piece molds are loaded with material manually, robotically, or through extruders. Once loaded, a press forces the mold closed, and pressure forces the material to fill the mold cavity.
In the compression molding process, many different types of recycled materials are used, including various plastics, rubber, synthetic resins, and other recycled waste products.
The rotational molding process dates back to the early 1970s. It begins with granular or powdered plastic material loaded into a shell-like mold. The mold is heated and rotated in two planes perpendicular to each other. This helps distribute and fuse the material to the mold.
The molds for rotational molding are usually cheaper than for other processes. The materials most commonly used to manufacture rotationally molded pallets are linear low-density polyethylene (LLDPE) and cross-linked polyethylene.
Profile extruded pallets look very similar to wooden pallets and are constructed similarly. The raw material is melted and then forced through an extruder. After cooling, the extruded material is cut to size like lumber and fastened with nails, screws, glue, or heat welds.
Industrial re-grind and post-consumer recycled material can be used to keep costs down, and the addition of wood fiber or other material to the extruded profile can add stiffness and help reduce.
Plastic pallets are basically used to carry cargo, so they are generally placed On the ground. It's been used for a long time, and it's inevitable to get dirty.
Wrong cleaning, not only not to achieve the cleaning, but also may cause damage to plastic pallets.
For normal cleaning
Drag the plastic pallets to an open place and point them at the plastic pallet with a clean pipe.
For stubborn stains
To soak with sodium hydroxide diluted and then scrub be used with a damp cloth.
It is not recommended to use stainless steel cleaning ball scrubbed, because the hard wire will cause scratches on the surface of the plastic tray.
For the square hole of pallets, we can scrub with a soft brush with some cleaning agent and warm water.
After cleaning, the pallet should be natural air-drying - to avoid direct sunlight.
Despite the durability of plastic pallets, we experience a few cases where pallets are deformed.
The overall stability of the deformed pallets is not only greatly reduced, but also makes some vehicles unmatched for use, resulting in a decrease in the carrying capacity of plastic pallets.
So what exactly causes plastic tray deformation?
1. Overweight.
Be sure to pay attention to its static load and dynamic load before we purchase.
2.The uneven distribution of the force points will cause the deformation of the plastic pallets.
For example, when placing the goods, the weight of the goods is concentrated in the edge of the plastic pallet part, and the middle does not carry the weight of the cargo, which will certainly cause the plastic pallet
deformation.
3. Incorrect handling operation.
Sometimes, the use of units in the use of plastic pallets to carry forklifts to operate goods, due to the problems of forklift drivers, will cause forklift arms to hit the plastic pallets, resulting in pallet deformation.
4.Encounter some bad pallet manufacturers that use defective materials to make the plastic pallets soft and fragile and deform.
It depends on the density of plastic pallets.
Plastic pallets are divided into PE type and HDPE type:
the density of PE is 0.89~0.91g/cm3 and HDPE is 0.941g/cm³~0.960g/cm³.
So the answer is Yes, all the common plastic pallets will float.
Plastic pallets are about 10 times longer than wooden pallets. In fact, steel pallets and plastic pallets are hard to distinguish in terms of life expectancy.
It's acid-resistant, alkali-resistant, corrosion-resistant, non-perishable.
It's nail-free, non-toxic, tasteless, non-combustible, no electrostatic sparks.
Plastic pallets are lighter than the same size wooden pallets, thus reducing the weight and cost of transport.
Plastic pallets can be cleaned and reused, and the U.S. Department of Agriculture is promoting companies
to use plastic pallets to carry products.
Now the EPA is aware that plastic pallets should be the preferred product for the U.S. Department of
Energy and the U.S. Department of Defense.
It's not only suitable for stacking each other in warehouses and on a wide range of shelves, but also suitable for all types of truck transportation, convenient material series, unitized transportation.
The plastic pallet is fumigation-free and can be used directly for export.
It's irreplaceable in some industries such as food, beverage, pharmaceutical, and other industries.
As a result of the damage resistance of plastic pallets, workers' compensation claims were reduced accordingly. And the reduction in the use of wood in the factory is equal to the reduction in fire insurance premiums.
Used plastic pallets can be sold at 30% of the original value, as they can be sold back to the manufacturer or other entities for reuse.
Plastic pallets are environmentally friendly because they can be recycled and reused, greatly reducing waste and disposal costs.
The use of plastic pallets can prevent the loss of thousands of acres of forest each year.
To use the plastic pallets, it can:
In short, the application of plastic pallets not only saves storage space but also greatly
improves the efficiency of storage management.
There are no plastic pallets manufacturers in Lagos so far.

Significantly, the larger the pallet weight, the more raw materials used, the higher the price.
The color of the tray can be tailored to the customer's needs, just add the corresponding color master material can be (common blue, meta color, green, red, etc.)
It can be divided into virgin material and recycled material. Their prices are very different.
A recycled material tray is a tray that adds a certain proportion of recycled raw materials;
The greater the proportion of recycled materials, the lower the cost and the lower the price.
Some pallets need to be formed after welding and other processes, the cost is of course higher.
In addition, the cost will be significantly increased when pallets added the anti-slip bars, steel pipes, RFID (built-in chips), or other pallets.
We should choose different material pallets depending on the situation in which we use them.
Different operating temperatures directly affect the selection of pallet manufacturing materials.
As the pallets of different materials have a temperature range that performs normally. For example, the operating temperature of plastic pallets is between 40 and 25 degrees C.
The trays of some materials cannot be used in humid environments due to their strong moisture absorption, such as wooden pallets, which will directly affect their service life.
We often need to consider the extent to which the pallets are contaminated using the environment.
In a highly polluted environment, it is important to choose a tray that is resistant to contamination and easy to clean. Such as plastic pallets, composite plastic wood trays, etc.
For example, spill control industrial plastic pallets are a better choice than wood pallets when we carry corrosive chemicals.
The appropriate pallet size should be just enough to meet the size of the means of transport, which can improve the full and reasonable use of the transport vehicle space, save transport costs, especially considering the container and truck case size.
