Processing for making PP packing box:
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.
Different configurations can be selected according to different needs of users.
