Explore our high-performance thermal shrink and heat sealable film portfolios curated for global commercial industries.
The global market demand for reliable, high-speed, and high-barrier polyolefin films is rapidly transforming.
Oriented Polypropylene (OPP) double-sided heat sealable films are the backbone of modern flexible packaging lines. Engineered via a multi-layer co-extrusion process (typically combining a core layer of homopolymer PP for strength and outer layers of copolymer PP for low-temperature heat sealing), these films are optimized to provide an exceptional operating window on high-speed VFFS (Vertical Form Fill Seal) and HFFS (Horizontal Form Fill Seal) machinery.
Unlike standard single-sided films, double-sided heat seal films feature symmetrical or asymmetrical heat seal layers on both surfaces. This offers maximum design flexibility for pouch geometries, lap sealing, and complex overwrap structures. By utilizing advanced slip agents and anti-static modifiers in the formulation, manufacturers can guarantee low coefficient of friction (COF) properties, facilitating smooth runs without film drag or structural distortion.

Discover how our multi-layered co-extrusion technology enhances seal integrity and speeds up production lines.
Core homopolymer layer provides tensile strength and rigidity, while double-sided terpolymer outer skin layers enable low-temperature sealing.
Engineered with high-performing migrating anti-static agents to prevent packaging dust attraction and film tracking issues.
Operating comfortably between 105°C and 145°C. Minimizes burn-through on heat seal jaws while maintaining absolute hermetic seal reliability.
| Property Parameter | Test Standard (ASTM) | Typical Value (OPP-2S Seal) | Benefits for Packaging Lines |
|---|---|---|---|
| Thickness (μm) | ASTM D2103 | 15, 18, 20, 25, 30, 40 (Customizable) | Optimized yield per roll and material cost management |
| Heat Seal Strength (N/15mm) | ASTM F88 | ≥ 2.5 - 3.8 (at 120°C, 0.2 MPa, 0.5s) | Leak-proof seals for powder, snack foods, and granules |
| Coefficient of Friction (COF - Dynamic) | ASTM D1894 | ≤ 0.30 (Film to Film / Metal) | High-speed machinery tracking, no jamming or slippage |
| Haze (%) | ASTM D1003 | ≤ 1.8% to 2.2% | Excellent gloss and transparency for retail visibility |

How local industries adapt and implement OPP double-sided heat seal films across regional climates and market demands.
In high-humidity regions (e.g., Southeast Asia, Latin America), our films act as an excellent moisture barrier, preventing biscuits, wafers, and breads from losing crispness, while remaining stable in warm warehouse storage conditions.
Designed for perfume boxes, cosmetics, and medicine cartons in Europe and North America. Double-sided sealing provides tight corners and a clean display, keeping products securely packaged during transport.
Specially formulated for Northern European and East Asian winters. Our heat seal films maintain flexibility and impact strength at low temperatures, preventing package splits along seals during cold storage transport.
Tianchen integrates advanced raw materials with streamlined logistics to provide consistent, stable lead times globally.
We source directly from Sinopec and ExxonMobil, ensuring consistent base resins for reliable production batches.
High-speed slitting lines deliver clean cuts with minimal dust, keeping roll edge tension consistent for your machines.
Films are wrapped with protective foam and suspended on pallets, preventing damage during long transit times.
Our facility in Zhongshan is close to major ports, allowing for fast, cost-effective container shipping globally.
Meeting international standards for food safety and environmental protection.
As a reputable supplier to global markets, Zhongshan Tianchen New Materials Co., Ltd. ensures that our packaging materials comply with key international regulations, including FDA 21 CFR 177.1520 for direct food contact, EU Regulation No. 10/2011, RoHS, and REACH requirements.
Every production run undergoes strict quality checks to verify chemical compliance, low migration, and absence of heavy metals. This ensures smooth customs clearance and supports our clients' product safety compliance across North America, Europe, Australia, and Asia.
