BOPP

BOPP film (biaxially oriented polypropylene film) is a film material widely used in cigarette packaging. It is widely popular due to its excellent physical properties and versatility.
1. **Material characteristics**:
– **Biaxially oriented**: BOPP film is biaxially (longitudinally and transversely) stretched during the production process, giving it better mechanical strength, transparency and toughness.
– **Lightweight and tough**: Compared with other plastic films, BOPP film has a lighter weight but excellent strength, and can provide excellent protection.
– **Environmentally friendly**: BOPP film can be recycled and has environmental advantages to a certain extent.
2. **Main features**:
– **High transparency and gloss**: Its surface is smooth, with high transparency and gloss, so it is particularly suitable for product packaging with requirements for appearance.
– **Excellent water resistance**: BOPP film has good moisture resistance, which can effectively prevent products from getting damp and extend the shelf life.
– **Chemical resistance**: BOPP film is resistant to most chemicals and oils, and is suitable for food, pharmaceutical and other industries.
– **Low permeability**: It has a certain barrier property against water vapor and gas, which helps to delay the oxidation and deterioration of products.
3. **Application fields**:
– **Labels and stickers**: BOPP film is often used to make transparent or opaque labels due to its gloss and excellent printability.
– **Tobacco packaging**: Its smooth and transparent characteristics also make it an ideal choice for packaging products such as cigarettes.
4. **Process and performance optimization**:
– BOPP film can be enhanced through different surface treatments, such as coating and aluminizing, to further improve its moisture resistance, air barrier and wear resistance.
– The thickness and structure of the film can be adjusted according to different application requirements to meet the personalized needs of different markets.
5. **Market prospects**:
– With the increasing global demand for environmentally friendly packaging, BOPP film has a steady growth in market demand due to its recyclability and superior performance, especially in the field of food, daily necessities and cosmetics packaging, and has broad prospects.
