There are still many materials for BOPP packaging film, and we are often used usual, so here we also introduce some of the more common types about it. I hope everyone can introduce this article through this article. It's clearer.
What are the common types of BOPP packaging film?
Pearl film: Most of them are three layers of stretching membranes. The surface is generally hot -sealing layer. It is common like chopstick bags. Often, the pearl film has its own hot sealing heat seal, so there will be a heat seal section. Unlike the BOPP light film, the density of pearl film is mostly controlled below 0.68, which is conducive to saving costs; and common pearls appear white, opaque pearl light effects, have certain light resistance, and protect products that need to avoid light. effect. Of course, the pearl film is often composed of other membranes in food and daily necessities, such as ice cream, chocolate packaging and beverage bottle tags. The white pearl light effect complements the carefully designed printing pattern.
Light membrane: Usually general light film is mainly printed and commonly used for packaging printing. Among them, it is divided into thick membrane and thin light film. Generally, thick film refers to the thickness of more than 25 μ, and the film refers to the thickness below 19μ.
Cover the light film: It is understood that the lithographic membrane is generally a thin light film under 18 μ, and it is generally double -sided electro -dizziness. Therefore, there is a re -coincidence area in use in use. Make ordinary bags.
Aluminum -plated film: It is relatively familiar with the aluminum -plated film, but there are many common ones with BOPET and CPP. At present, domestic BOPP aluminum plating is relatively rare. Especially in recent years, with the price advantage of BOPET, the BOPP aluminum plating market has affected to a certain extent that it has affected to a certain extent. Essence
Viructuary: also known as the sub -light film, which is mainly achieved by absorbing and scattering of light. Generally, it can improve the grade of the printing appearance, but the price is relatively high, and there are fewer domestic manufacturers. Therefore Use in packaging. The light -consuming film is often used without heat seal, so it is used in composite use in other membranes (such as CPP, BOPET).
Laser membrane: It is a functional layer with analogytable, transparent BOPP film, and can achieve mold pressure without an additional mold pressure layer. It is used for anti -counterfeiting packaging after aluminum plating or steaming medium, or it is used as cigarettes with cardboard or non -grinding composite as cigarettes. , Pharmaceutical, food and other packaging boxes. It is relatively small in domestic production. It is generally used for high -end commodity anti -counterfeiting, decorative packaging, etc., and has certain requirements for production technology.
These are the common types of BOPP packaging film that often use in life. Do you have an introduction to you after you introduce it? If you need to buy the BOPP film, you must remember to contact the phone to contact the phone call. us.
