Made from high-quality polypropylene resin using an advanced multilayer co-extrusion process, BOPP Automatic Packaging Film combines high transparency and excellent printability with optimized coefficient of friction (COF), mechanical stiffness, and heat-sealing performance. The printing surface features high-intensity, uniform corona treatment with a wetting tension of ≥38 mN/m. Whether used with conventional dry lamination or environmentally friendly solvent-free lamination processes, the film provides strong compatibility and helps build an effective moisture and environmental barrier, supporting the crisp texture and quality of dry food products throughout storage and transportation.
With precision surface slip treatment, the internal and external coefficient of friction (COF) is carefully controlled for stable film feeding. Even at speeds of several hundred packs per minute, the film runs smoothly across metal components such as forming wheels and guide rails, helping prevent sealing-knife sticking and film jams.
The film features very low thermal shrinkage and excellent mechanical stiffness. During high-speed bag forming and filling, it helps maintain compact, flat, and wrinkle-free packages while minimizing print registration deviation and misalignment in multicolor printing.
The heat-sealing layer features a low initial sealing temperature and excellent tolerance to contaminants during heat sealing. Even when food powder or grease is present around the sealing area, the film can maintain a strong and flat seal, significantly reducing reject rates during high-speed packaging operations.
The surface features optimized corona treatment for excellent ink adhesion. Whether used for flexographic or gravure printing, the film delivers high-contrast and realistic graphic reproduction. Combined with its high light transmittance, it enhances the overall visual appeal of packaged products on retail shelves.
A specially formulated anti-static system helps dissipate static electricity generated by high-speed friction, reducing dust attraction and preventing the film from wrapping around or accumulating on machine components. This supports smoother and more stable continuous production on automated packaging lines.
Suitable for puffed foods, biscuits, candies, nuts, and other snack products. The film is well suited to various pillow packaging machines and vertical form-fill-seal (VFFS) machines, supporting stable film feeding and reliable sealing during high-speed production.
Suitable for facial masks, hair and body care products, tissue outer packaging, and other daily chemical applications. It provides reliable sealing performance together with a bright, attractive appearance.
Suitable for pharmaceutical tablets, dietary supplements, individually packed face masks, and other healthcare products. The film supports secure sealing and packaging integrity during high-speed automated packaging while helping maintain the clarity of printed identification and anti-counterfeiting information.
Suitable for frozen dumplings, frozen pastries, and other frozen food products. The film maintains excellent flexibility and reliable heat-sealing performance under low-temperature conditions, supporting package integrity throughout cold-chain storage and transportation.
As medical supply market access requirements and e-commerce logistics inspections in multiple countries become increasingly stringent, a multinational medical consumables exporter encountered repeated packaging problems when operating a fully automatic high-speed pillow packaging machine at more than 250 packs per minute.
Conventional films frequently experienced instantaneous thermal perforation and melt fracture/stringing at the sealing area during high-frequency sealing. In addition, excessive thermal shrinkage caused uneven package surfaces and distorted printed anti-counterfeiting barcodes during scanning, negatively affecting customs clearance and logistics efficiency.
For the customer's ultra-high-speed automated packaging line, HUA HENG's technical center developed a customized 20–25 μm BOPP Automatic Packaging Film.
Ultra-Wide Heat-Sealing Window & Low-Friction System: Through precision slip treatment of the surface layer, the coefficient of friction (COF) was stabilized at ≤0.25. This enabled smooth film feeding and excellent resistance to thermal shear during high-frequency pulling and instantaneous sealing at speeds exceeding 250 packs per minute, helping prevent sealing-knife sticking, film jams, and thermal perforation.
The film also features very low thermal shrinkage and high tensile stiffness, with MD tensile strength reaching ≥120 MPa. This helps maintain a compact, flat, wrinkle-free package after forming, while ensuring that printed medical protection markings and traceability/anti-counterfeiting barcodes remain accurately reproduced without registration deviation.
After the medical consumables company switched its entire packaging line to HUA HENG BOPP Automatic Packaging Film, the overall reject rate of the high-speed automated packaging line dropped from 4.2% to below 0.1%.
The sealing integrity rate and heat-seal strength remained stable, with heat-seal strength reaching ≥2.0 N/15mm. This effectively addressed customer complaints in overseas markets concerning bag failure and air leakage that could lead to cross-contamination, while enabling the customer to increase packaging-line speed and overall production efficiency.
No. The heat-sealing layer of HUA HENG's BOPP Automatic Packaging Film is formulated for excellent contaminant-tolerant heat-sealing performance. During the extremely short sealing cycle at 120°C for 0.3 seconds, the molten sealing layer rapidly flows around and encapsulates small amounts of powder or grease present in the sealing area.
With heat-seal strength maintained at ≥2.0 N/15mm, the film supports strong, flat, and reliable seals even in packaging environments where fine powders or small amounts of grease may be present, helping reduce the risk of air leakage and sealing defects.
HUA HENG utilizes the heat-setting and crystallization technology of German Brückner production lines to provide the film with excellent mechanical stiffness and very low thermal shrinkage. Combined with precise thickness control and extremely low thickness deviation, the film maintains dimensional stability during high-speed machine pulling and continuous heat sealing.
This helps keep the sealing area flat and wrinkle-free while maintaining accurate reproduction of printed graphics and minimizing print registration deviation during high-speed packaging.
The film is packaged using a suspended shaft or paper tube core, together with moisture-proof film, stretch film, and pallets. This packaging configuration is suitable for long-distance ocean and land transportation.
The standard lead time is 15–20 days after order confirmation. For conventional specifications with safety stock available, delivery can be shortened to 7–10 days.
