2450mm PP PE PC Hollow corrugated box sheet making machine China Manufacturer Tongsan

PP plastic hollow plate is a new type of environmental protection products, no pollution, no harm, meet the requirements of green environmental protection. The product has large internal quality, flat surface, high breaking strength, flame retardant, good moisture-proof performance, zero surface water and steam penetration, heat insulation, good energy saving effect. Especially the refrigerator with external condenser has excellent adiabatic effect. The company can make all kinds of refrigerator, freezer, washing machine back and base according to customer's request

Comparing of canton packing material and PP hollow sheet material
1, Paper - paper fear of water, fear of tide, perishable, can not guarantee the quality of the product transport, there may be increased costs, so most of the cartons, cartons, cardboard and other paper products can only be used once. 
2, PP hollow sheet related products can be flexibly produced, compared to the expensive plastic injection box, PP hollow sheet box cheaper many, customized according to customer size, thickness, toughness, hardness, printing, etc. 
3, Traditional cartons will be broken after several times of using, the PP hollow sheet  crates life is about 20 times of the carton material, or even longer, it can reduce the using cost greatly.  
4, And the PP hollow sheet products are non-toxic, pollution-free, environmental protection, waterproof, moisture-proof, shock absorption and other characteristics, compared with traditional cardboard, wood, easy to use, easy to store, can be reused, long life, but also recycling, Higher social and economic value. 

PP hollow sheet turnover box main material is a PP hollow sheet, and then after the pressure cut, torn edges, stitching, assembly and made of a series of processing flow.

Below is the example of processing for turnover box

1, the extrusion line produce the required PP hollow sheets with required width and thickness, and cut into required length. And collecting different sizes in different stacking.

2,Use the  pressure cutting machine to cut the PP hollow sheet into required  shape. Pressing action should be accurate, rapid, agile, and keep the board clean, in accordance with the provisions of a unified placed on the table

3, the professional workers tear the extra edges according to the indentation from the pressure cutting machine, The tearing action should pay attention to the intensity. to ensure the board neat appearance, it is not allowed to produce flash and laceration because of strong tearing force.

4, stitching the two sheets by rivets, flat wire or welding, etc., the stitching seal can be sealed by  fiber tape or glue or magic paste.

5, quality inspection. Quality inspection staff to perform full inspection, sampling, failure and other standard scrap process.

6, the qualified products will be packaged and stored, when folded, the packing box should be labeled and neatly put into storage.

The above is the whole process of making the turnover box from the PP hollow sheet. The turnover box made from PP hollow sheet has the advantages of light weight, non-toxic, tasteless, no pollution, flexural resistance, anti-aging, waterproof, moisture proof, abrasion resistance, corrosion resistance, , Can be reused repeatedly and a series of advantages, is a new type of green materials, logistics and packaging industry in the transport plays an important role in storage and turnover, can effectively protect the product from the external environment damage
