1. 150m/min high speed has already reached the international most advanced level.
2. Rewind and unwind both adopt double position and equip with semi-automatic to connect paper device, The machine can change the rolls of base material nonstop， It will reduce the waste.
3. When the double sides adhesive tape coat twice, it will effect the quality of products, but the technology of double sides coating meanwhile will solve the questions.
Nylon film is a kind of paper that is very easy to absorb moisture. It will have adverse effects on the use after moisture absorption. For example, the dimensional change causes the overprinting to be inaccurate during printing, and the water film on the surface causes insufficient composite strength, foaming, etc. The nylon film should be protected from moisture in a high humidity environment. Specifically, pay attention to the following aspects:
(1) Do not open the package too early before use.
(2) Run out as much as possible, and leave the remaining film with a good barrier material.
(3) The first color group is not printed on the plate during printing, and pre-drying is performed.
(4) Put in a curing chamber for 2-3 hours before use.
(5) Ensure a reasonable temperature (25 °C ± 2 °C) and humidity (≤ 85% RH) in the production workshop. Biaxially stretched nylon film (BOPA film) is a new type of high-grade packaging material. Compared with traditional polyvinyl chloride film and polyester film, it has excellent resistance to cracking, impact, puncture and odor barrier. It is widely used as packaging materials in the fields of food processing, medical and health, chemical products, etc. It is especially suitable for frozen packaging, vacuum packaging and retort packaging. The preservation and fragrance of foods are far greater than conventional packaging materials.
Note on the use of the coater:
1. Clean the surface of the roller and the coating tool with alcohol before starting the machine.
2. Start the “Scraper Lock” button before adjusting the blade gap. Coating should be carried out in strict accordance with the process requirements to meet the process requirements.
