Standard Thickness Heat Sealable BOPP Film is manufactured using high-quality homopolymer polypropylene resin through precision biaxial orientation and multilayer co-extrusion processes. The heat-sealing layer uses high-performance heat-sealing masterbatch, giving the film a stable heat-sealing window and good hot tack performance. During high-speed packaging, the seal can fuse rapidly, reducing the risk of seal rebound, leakage, and package breakage. The film also provides good thickness uniformity, a stable surface coefficient of friction, excellent slip, and good opening performance, helping reduce film deviation and knife sticking during high-speed bag making while improving continuous production stability and lowering overall packaging costs.
18μm–30μm is the conventional thickness range for general-purpose packaging. Suitable specifications can be selected according to different packaged products and equipment requirements. The film combines good tensile strength, stiffness, and flatness while maintaining sufficient flexibility, making it suitable for various forming collars, bag-making machines, and automatic packaging equipment.
For high-speed packaging applications, stable thickness uniformity and surface coefficient of friction help maintain smooth film feeding and stable bag-making operations, reducing the risks of film deviation, knife sticking, and production interruptions.
The surface layer uses high-performance heat-sealing masterbatch to provide stable low-temperature initiation and a wide heat-sealing window, together with good Hot Tack strength. During high-speed packaging, the seal can fuse rapidly and remain stable, reducing the risks of seal rebound, air leakage, liquid leakage, and package breakage. This makes the film particularly suitable for automatic packaging lines requiring high continuous production efficiency and sealing stability.
Using high-purity resin and precision biaxial orientation technology, the film provides high light transmittance and low haze, allowing the color and appearance of packaged products to be clearly displayed.
At the same time, good gloss enhances the visual appearance of the package surface, providing better shelf presentation for food, daily chemical, stationery, and other products.
The film surface undergoes optimized corona treatment, with wetting tension reaching ≥38mN/m, which helps improve ink adhesion. The film is suitable for flexographic and gravure printing and can also be used as an outer substrate for dry lamination and solvent-free lamination processes, meeting the requirements of different flexible packaging structures and printing processes.
The film is manufactured using a mature multilayer co-extrusion process and equipped with an intelligent online thickness measurement system for continuous monitoring. Thickness deviation is strictly controlled within ±0.5μm. Stable thickness control helps improve film running consistency during high-speed bag making, packaging, and lamination, reducing processing efficiency losses and material waste caused by thickness fluctuations.
Customized film solutions are available according to different packaging equipment, production speeds, and packaged contents. Film thickness, heat-sealing temperature, and coefficient of friction can be adjusted according to actual production requirements. Single-sided and double-sided heat-sealable structures are also available.
Conventional specifications are maintained in safety stock. The lead time for regular orders is approximately 15–20 days, while certain stocked specifications can be delivered within 7–10 days. The MOQ is 1,000kg. Packaging options include suspended shafts or paper cores combined with moisture-proof film, stretch film, and pallet packaging, making the products suitable for long-distance sea and land transportation.
