BOPP film and BOPP pearlescent film usage:
1)BOPP film has glossy film and matte film. Bright film is brighter and has rich colors; matte film is darker and has stable quality.
2)BOPP pearlescent film material is made of polypropylene resin as raw material, mixed with calcium carbonate and pearlescent pigments then stretched in two directions to be a film.
Due to the mechanical foaming method, the specific gravity of pearlescent film is only about 0.7, while the specific gravity of polypropylene is about 0.9, so flexible packaging companies are willing to choose this pearlescent film because it is cheap, decorative and excellent performance.
3)Characteristics of BOPP pearlescent film
The pearlescent film has a silver-white pearlescent color, can reflect more light. BOPP pearlescent material and bags has excellent gas barrier, water barrier and light barrier properties (especially for UV light barrier). It has excellent protective effect on products that need to be protected from light.
Unlike BOPP film, the density of pearlescent film is mostly controlled below 0.68, which is beneficial to cost savings.
Pearlescent film is a thin film material with many usages.
1)Pearlescent film generally composite PP woven fabric, Polypropylene, BOPP pearlescent film/PE/CPP/Alu etc.
Due to its certain pearlescent effect, it is often used in cold drink packaging, such as ice cream bags, heat seal labels, sweets packaging, biscuits sacks, flavored snack packaging, some people use it for high value products like chemicals, pigments etc.
2)Protection and packaging: Pearlescent film has good anti-extrusion properties and can effectively protect the items in the package. Especially for fragile items such as glass products and electronic products, it can prevent damage during transportation.
3)Waterproof, moisture-proof and dust-proof: Pearlescent film facilitates the packaging, storage and logistics transportation of items, especially in humid climates or rainy days, it can keep the performance of items from being affected.
4)Decoration: Pearlescent film has good decorative properties due to its unique pearlescent effect. It is often used to enhance the visual effect of product packaging and attract consumers’ attention.
5)Environmentally friendly and durable: Pearlescent film is environmentally friendly and durable, with good tear resistance and excellent stiffness. It is suitable for a variety of printing methods, such as flexo, letterpress, offset printing and screen printing, and has high color reproduction.
6)Special applications: Pearlescent film can also be used in automobile color-changing films, cold drink packaging and other fields, such as car body color-changing films, because it emits sparkling pearlescent light in the sun, making the car body more dazzling; in cold drink packaging, pearlescent film is unique because of its uniqueness. The pearlescent effect and excellent barrier properties have become the new favorite of packaging nowadays.
