Why does bubble film cross flow?
That is, the two films are not well adhered. This one is a little difficult to adjust. It is not cross-linked and has rotten bubbles. This needs the master's skill.
The second is bubble film, also known as air cushion film, bubble glue, bubble roll, etc., which is made of low-density anti-static bubble roll polyethylene. It is a kind of transparent flexible packaging material widely used at present.
Its principle is that the film contains air to form vapor bubbles to prevent product impact, to ensure that the product will play a protective role in the event of vibration, but also has the role of thermal insulation, suitable for different products of all walks of life packaging or turnover! Because the middle layer of the bubble film is full of air, it is light and elastic. It has the performance of sound insulation, shock resistance and wear resistance. It is waterproof, moisture-proof and compression resistant.
Bubble film can be divided into single side and double side. Single side bubble film is suitable for protecting light weight products, and double-sided bubble film has strong shock resistance and is suitable for packaging large and heavy articles. Single and double-sided bubble bags are suitable for both new materials and return materials. The quality of new materials is certainly better, but the cost will be relatively high. If you only mail things under packaging, you can choose to use about 80% of the new materials. Only 20% of the returned materials are added in this material. The quality is also very good. There is enough air in the bubbles, and the cushioning and compression effect is also very good! In this way, your packing cost is also reduced a lot.
