As an "important role" in commodity circulation, packaging must well meet and serve the requirements of cushioning and anti-seismic packaging of internal commodities. Nowadays, with the bubble bag becoming more and more popular, the bubble bag produced in the market has various materials and different quality. So, what is the material of bubble bag? How to distinguish the quality of materials?
What material is bubble bag? Bubble bag material quality discrimination Guide
1、 PA bubble bag
PA is a kind of (PE + PA, PA) bubble bag with strong pressure bearing and tensile properties, which can be used in heavy-duty products, large-scale products or products requiring enhanced protection. Generally, we make PA bubble bags with valves, which can be inflated manually or automatically by machines.
2、 Po bubble bag
Po material is HDPE, the bubble bag made of high-density polyethylene is milky white and has strong impact resistance. This kind of material bubble bag is usually made into a valveless one. When inflating, the sealing machine needs to seal and inflate at the same time. Because of the relatively low price, obvious buffer capacity and automatic inflation, many businesses and enterprises will choose this kind of material bubble bag for shipment now.
3、 PE Bubble Bag
PE is LDPE, low-density polyethylene. This material is transparent, soft and beautiful. The material can be made into a bubble bag with or without a valve, which depends on the needs of customers.
According to the experience, the high-quality bubble bag mainly uses high-quality PE + PA (nylon) film in the selection of basic materials, which belongs to polyethylene material. High Nylon content, good ductility. The raw materials used are safe, non-toxic, recyclable and free from environmental problems. The bubble film is smooth and fine, with good surface printability. The gas packaging bag passes the ISO 140001 standard and conforms to the RoHS specification; the poor materials are usually recycled materials, with yellow color, dark color, rough texture, or the behavior of reducing the quality standard that damages consumers. Nylon content is low. It will burst when you squeeze hard.
