BOPP comparison PET
BOPP and PETare two common Food Packaging materials, each with different characteristics and application scenarios.
BOPP (biaxially oriented polypropylene film)
BOPP is a colorless, odorless, tasteless and non-toxic flexible packaging material with high tensile strength, impact strength, rigidity and toughness. It occupies an important position in the packaging field and is widely used in the packaging of food, medicine, clothing and other products. BOPP film has the following characteristics:
- Transparency and printing performance: BOPP has good transparency and is suitable for a variety of printing methods. The printing effect is bright and saturated, and is suitable for packaging of food, cosmetics, etc.12.
- Physical properties: BOPP has good elasticity and softness, is suitable for use on irregular surfaces, and works stably at room temperature1.
- Cost-effectiveness: BOPP materials are more environmentally friendly during the production process, and the end products can be recycled.
PET (polyethylene terephthalate film)
PET is a packaging material with high transparency, good gloss, excellent mechanical properties and barrier properties. It is often used in situations where high transparency and high temperature resistance are required. Features of PET film include:
- Transparency and visual effects: PET has higher transparency and provides clearer visual effects, which is suitable for occasions where the content behind the label needs to be displayed.
- Temperature resistance and hardness: PET has better temperature resistance and can withstand high temperature environments within a certain range. It is suitable for application scenarios that require high temperature resistance, such as high-temperature cooking bags, microwave bags and other fields.
- Environmental performance: Although PET is not as good as BOPPin terms of environmental protection, it has high stiffness and good durability, making it suitable for outdoor or high-quality Packaging Bags.
In general, ZL-PACK BOPP/PET is a very good food packaging bag material because they have the advantages of durability, moisture-proof, oil-resistant, high clarity, good stiffness, etc., and can protect freshness of food.
