Double Sided Heat Sealable BOPP Film

Double Sided Heat Sealable BOPP Film is a biaxially oriented polypropylene (BOPP) packaging film with heat-sealing functionality on both sides, designed specifically for versatile packaging applications and high-speed packaging equipment.

The double-sided heat-sealable structure can be flexibly used for center-seal bags, back-seal bags, gusseted bags, four-side-seal bags, and multilayer laminated packaging, meeting the sealing requirements of food, non-food, and flexible laminated packaging applications.

The film combines double-sided heat sealing, high transparency and gloss, good mechanical strength, puncture resistance, moisture and barrier properties, and good printability.

Technical specifications include customizable thicknesses of 15μm–50μm, customizable widths of 350mm–2500mm, heat-seal strength of ≥2.0 N/15mm, machine-direction tensile strength of ≥120 MPa, transverse-direction tensile strength of ≥220 MPa, and haze of ≤4%. Specifications can be matched according to customer packaging structures and production equipment.

Multiple Packaging Formats

Both sides of Double Sided Heat Sealable BOPP Film provide heat-sealing functionality. Compared with single-sided heat-sealable structures, it offers greater flexibility in packaging design and sealing methods. It is suitable for center-seal bags, back-seal bags, and multilayer laminated packaging, as well as stand-up pouches and single-unit product packaging.

The film provides high transparency and gloss with a smooth surface, helping clearly display packaged contents and brand visuals. This makes it suitable for food and consumer product packaging where shelf presentation and package appearance are important.

The ability to heat seal on both sides makes the film convenient for sealing different packaging structures. It can be used not only for center-seal bags, back-seal bags, gusseted bags, and four-side-seal bags, but also as an inner or outer substrate in multilayer flexible packaging structures. Overall, it is well suited to high-speed packaging applications requiring reliable sealing and attractive package appearance.

Specific applications include:

Food Packaging — Suitable for snack foods, candy, bakery products, frozen foods, and fresh agricultural products.

Non-Food Packaging — Suitable for textiles, stationery, toys, and hardware accessories.

Laminated Packaging — An ideal inner or outer substrate for multilayer flexible packaging structures.

Bag-Making Packaging — Suitable for back-seal bags, gusseted bags, four-side-seal bags, and other packaging formats.

Reduce Damage During Transportation and Handling

Double Sided Heat Sealable BOPP Film provides high tensile strength in both the machine direction (MD) and transverse direction (TD), together with puncture resistance and durability, supporting the mechanical stability of packaging during production, handling, and transportation.

The machine-direction tensile strength is ≥120 MPa, while the transverse-direction tensile strength is ≥220 MPa. Its good puncture resistance makes it suitable for packaging applications requiring a certain level of mechanical durability.

The film is manufactured using precise thickness control technology, and every roll is strictly tested to maintain consistent film performance. Stable thickness control helps the film run smoothly on high-speed packaging equipment, reducing abnormal conditions such as film jamming and misalignment.

1.Precise thickness control maintains stable film specifications.

2.Every roll is subject to strict testing.

3.The product complies with international packaging standards.

4.Sufficient production capacity supports orders of different scales.

Multi-Specification Customization and Technical Support

For different packaging structures, equipment, and production requirements, customization is available for thickness, width, and roll diameter. Our technical team can also assist with material selection and equipment parameter optimization.

Thickness customization: 15μm–50μm; width customization: 350mm–2500mm. Roll diameter customization is available, allowing material selection and parameter optimization according to actual packaging equipment and material structures.

What Advantages Does Our Double Sided Heat Sealable BOPP Film Have Over Other BOPP Films?

Our advantages are first reflected in our standardized and environmentally responsible manufacturing capabilities. As a municipal-level green factory, we integrate green manufacturing principles into production management. Through standardized production processes and resource management, we continuously focus on energy utilization, resource consumption, cleaner production, and greener products, providing a reliable manufacturing foundation for stable film production.

Secondly, our film offers excellent printability. The corona-treated surface provides reliable ink adhesion, making it an excellent substrate for high-quality flexographic and gravure printing.

The film also provides strong moisture and barrier performance, helping effectively block moisture and humidity and significantly extend the shelf life of packaged products.
