Beautifully printed Bopp packaging bags

Biaxial polypropylene (BPP) packaging bag is a kind of high performance plastic packaging material, made by biaxial drawing process, with excellent physical properties and a wide range of application scenarios. Its core material is polypropylene (PP), after stretching treatment, the molecular structure is more compact, giving the bag higher strength, transparency, moisture resistance and printability. Such bags are commonly used in the packaging of food, daily necessities, industrial products and agricultural products.

Core features 

1. High strength and durability

After bidirectional stretching, the tensile strength, puncture resistance and wear resistance of BOPP film are significantly improved, which is suitable for transporting and storing heavy objects (such as grain, fertilizer, building materials, etc.).

2.  Moisture-proof and waterproof 

The smooth and completely sealed surface of the BOPP film effectively insulates moisture, moisture and contaminants, protecting the contents from environmental damage.

3. High transparency and gloss 

- The transparency of BOPP material is close to glass, which can clearly display the contents of the packaging, while the surface gloss is high, which improves the attractiveness of the product shelf.

4. Good temperature resistance 

- Stable performance in high or low temperature environments (-20°C to 120°C), suitable for frozen foods or products requiring high temperature sterilization.

5.  Printing adaptability 

- BOPP film surface is flat, can be high-precision color printing, bright and lasting patterns, suitable for brand customization and product information annotation.

6.  Lightweight and environmental protection 

- Compared to traditional packaging materials (such as glass, metal), BOPP bags are lighter, lower transportation costs, and recyclable, in line with the green packaging trend.

Main application areas 

-  Food industry  : Packaging of dry or moisture-proof products such as snacks, candy, frozen food, rice, flour, grain and oil.

-  Agriculture and Chemical Industry : moisture-proof and leakproof packaging of seeds, fertilizers, feed and chemical raw materials.

- Industrial products : Dustproof and anti-oxidation protection for building materials, electronic components and mechanical parts.

- Daily necessities : Sealed packaging of laundry detergent, detergent, cosmetics and other daily necessities.
