1. The paper tubes must be aligned. One side cannot be extended, and the other side is short. The standard for each side of the stretch film is about 1 cm.

 

2. Minimize the surface folds at both ends, and the white pressed lines in the middle (otherwise, it will seriously affect the aesthetics).

 

3. There are no black impurities, the die head should be washed cleanly, and no burnt plastic will fall into it. If the naked eye can find it, it must be removed immediately.

 

4. When packing, be careful not to collide with the edge, cause the edge to break, and cause quality problems, and there should be no burrs.

 

5. If the scrap is broken, it should be cut neatly. If the cut is uneven, it cannot be shipped as a finished product. Including when making goods, both ends must be rolled up neatly, not more on one side and less on the other. The heat-shrinkable film has good performance, a wide range of welding and sealing, and good low-temperature weldability.

 

The heat shrinkage rate of stretch Film is >50%, and it has the proper heat shrinkable film molding machine capacity for various special-shaped products, and the packaging is natural. The unique oxygen barrier layer produced by the three-layer composite is airtight, impermeable, has good barrier properties, and is not easy to be contaminated with dust; high transparency and good gloss, which can further improve the packaging grade of the product, the product has good heat sealing, and homework is easy. , not easy to break the membrane.

 

The application of stretch Film is pervasive. In addition to its industrial role, it is also used in agriculture as an agricultural mulch film. It has high performance, multi-functionality, and low cost of stretch film. The agricultural mulch film is made of high-quality plastic materials because various additives are reasonably added so the equipment can be kept in good operation and the processing technology is scientific and correct.
