Plastic pallets manufacturers

Plastic pallets selected 100% high impact strength high density polyethylene (HDPE) or polypropylene (PP) as raw materials processing and applied backlash technical design, high strength, impact resistance, good endurance, long life (anti-aging agent added). That is why its life is several times over that of ordinary wooden pallets. In addition, because of its durability, buyers will be able to recover costs of plastic pallets after three years.

Compared with same carrying capacity wooden pallets or steel pallets, plastic pallets have advantages of light weight, smooth, beautiful, no nails or thorns, non-toxic and tasteless, acid and alkali resistance, no spark, explosion-proof, non-slip, and high recycling prices. Even after years of use, plastic pallets will still be able to maintain original size, rigidity and strength. Especially ideal for using in high shelves and stereoscopic warehouses.

As we all know, while using wooden pallets and steel pallets, there is possibility of risk. Plastic pallets can guarantee safety of users long- term use, widely used for transporting food, pharmaceuticals, chemicals, small machinery, electronic products, rubber, fertilizer, and feed at ports, terminals and factories. companies Ideal packaging equipment, warehouse handling good assistant.

1. Plastic pallets size selection

When choosing plastic pallets, depending on different requirements, and different product sizes placed, selecting standards are different.

I. First consider packing of goods and placed way on pallets, for instance, standard size of European turnover boxes is 600 × 400 mm. on the surface of 48" × 40" plastic pallets, a layer can be placed with 5 pieces turnover boxes, on the surface of 1200 × 800 mm plastic pallets, can be placed with four pieces turnover boxes and generally be stacked with five layers. Another example: Japanese standard turnover boxes size is 530 × 365 mm and 650 × 440 mm, on the surface of 44" × 44" pallets, one layer can be placed 6 and 4 pieces, generally stacking five layers. Of course, if the product is not stored inside of turnover boxes, they would have to choose plastic pallets according to original packaging size of pallets.

II. Consider pallet loading tools (such as containers, trucks, etc.). For example: If you use as round-trip or one-time, we need to give priority to the applicability of the width 2300 mm of shipping containers. Combination display of pallets with length 1200 mm and width 1000 mm, you must use 4 into the fork. For 1200 × 800 mm pallets, with 800 mm width direction placed two side by side. For 44" × 44" pallets, with 1100 mm width, placed two, 2 or 4 into the fork can be.

III. Or using on warehouse shelves need to consider the width and depth of shelf. Such as more common rack beams, each layer each cargo space place two pallets, leaving around 100mm space around, put the large size of pallets on the depth of shelf, will not demand strict carrying capacity of plastic pallets, in order to save procurement costs, as 1210 plastic pallets, depth is 1200 mm, so the outside of beam width is 1000 ~ 1100 mm, inside width 900 ~ 1000 mm. 1210 common racking pallets, steel pallets and heavy duty reversible plastic pallets 1210.

IV. Or use automated warehouse, in addition to meeting the above requirements, Also need to consider non-slip coefficient of pallet surface, and pallet leg and bottom fit with chain transfer device. Fork hole height, fork width and carrying capacity on evenly placed on the shelves, amount of permanent deformation, the length of the surface deflection, Bar-code pasted position, RFID chip placement and other factors.

V. Plastic pallets selection should also consider universal property of pallets size, pallets sizes commonly used in China are the 48" × 40", 1200 × 800 mm, 44" × 44", 1300*1100 mm and 1400*1100 mm five types, accounting around 70% of overall pallets sales, the remaining 30% share is some of the less commonly used sizes and professional products of industries (Such as 1250*1000 mm tobacco dedicated pallets).

2. Single deck plastic pallets or reversible plastic pallets?

I. Single deck pallets can be used on front side, whose surface have two types, one is mesh, the other type slat surface. Single deck pallets bottom design are divided into 3-runners, 9-skids and cross shape. With regard to carrying capacity and occasion, they are divided to racking pallets, standard pallets and light duty pallets as well.

II. Front and back deck structure of reversible plastic pallets are the same, both deck can be exchange used, mesh and slat surface both available, and are divided to racking plastic pallets and standard pallets according to carrying capacity.

III. Choosing single deck plastic pallets or heavy duty reversible plastic pallets should according to the corresponding storage requirements, handling equipment and state (such as the storehouse type, shelf type, stacking or place status, etc.) to determine.

IV. For a relatively small footprint auto stereoscopic storage warehouse or high shelves, electric stackers and fork with vertical transfer based occasions, single side plastic pallets and reversible racking plastic pallets can be selected.

V. If the load on automated warehouse or on the shelf need to arrive at 1 ton or more, and no mat boards on the shelf, we recommend using the built-in steel tube mesh pallets or flat racking pallets, built-in galvanized steel structure pallets, effective solution to the problem that the larger shelf load, the larger self weight, the higher product cost. Use rigid pipe 2mm wall thickness, reached stringent requirements of stereoscopic storage warehouse horizontal and vertical deflection ≤6mm.

VI. For large area and horizontal transport-based cases, use hydraulic vehicle handling, should select single side pallets. Requiring stacking of goods, and bottom of pallets coincide with above of cargo below, use reversible plastic pallets or swastika trays better. If using a forklift handling goods, use nine foot pallets or single side pallets is suitable.

3. Plastic pallet loading requests

I. Dynamic load refers to use manual hydraulic vehicle or forklift truck, maximum lifting weight allowed, generally shelf pallets carrying 1.5 tons, standard pallets carrying one ton, light pallets carrying 0.5 tons.

II. Static load refers to the maximum weight that bottom plastic pallets can bear during stacking process, generally shelf pallets can load six tons, standard pallets can load 4 tons, and light weight pallets two tons.

III. Shelves bearing weight means the maximum allowed weight that placing plastic pallets of evenly placed cargo on the shelf. Be sure to pay attention to the difference of dynamic load, static load and Stereoscopic shelf bearing. Different carrying capacity are closely related with shelf structure, placing form, ambient temperature and storage period. Generally shelf pallets can load 0.7 tons - 1.0 tons on beam shelves. Standard pallets load is 0.2 tons to 0.4 tons.

IV. Shelves have certain requirements for Permanent deformation and deflection of plastic pallets .National standards for the maximum deflection is 30mm, but this data is noticeably wide. We recommend maximum deflection of using plastic pallets on the shelves should be no more than 15mm, so as to ensure the safety of largest production and operations. For automatic warehouses, deflection requirements is even more stringent, usually within 6 mm.
