PET material plastic box is now more and more favored by customers, because of its transparent, safe and environmentally friendly qualities, has gradually replaced PVC to become the main material of the plastic box process, look back on the process of PET box manufacturers in the past years, PET stick The glue process can never be sticky, it can be very whitish, it can be slightly white, and it can be completely transparent. It can also be a twist.

      Prior to 2006, there were relatively few customers using PET as a plastic box. At that time, the conventional APET material could not be bonded, and it was necessary to use a very expensive GAG to produce the entire package. PVC has more than doubled, so it is not for customers with high environmental protection requirements. Basically, it is discouraged. Afterwards, there is a process to develop a special glue that can stick PET. It can stick, but it is very heavy and it will turn white. The product has relatively high sanitary requirements. This is not feasible. In the next year or two, the plastic box machine has made some improvements, instead of spraying glue, reducing the amount of glue used to reduce the stickiness of the product. The process is also rampant, but the production efficiency is relatively low, and the quality is not stable.

      The PUR adhesives developed in the past two years are used for the bonding of PET plastic boxes, which greatly improves the bonding technology, the paste edge is completely transparent, and there is no odor, safety and environmental protection.
