High Strength Heat Sealable BOPP Film is an ideal choice that combines premium visual presentation with reliable packaging sealing performance. Manufactured from high-purity polypropylene resin using a precision biaxial orientation process, the film is designed to address common flexible packaging issues such as ink removal and air leakage. The non-heat-sealable side undergoes uniform surface corona treatment (≥38 mN/m), providing excellent ink adhesion and coating compatibility. Meanwhile, the heat-sealing layer offers excellent Hot Tack strength and a relatively low initial sealing temperature.
During high-speed automated filling and packaging processes, film thickness deviation is strictly controlled within ±0.5 μm through an intelligent online thickness measurement system, helping ensure accurate multicolor printing registration and smooth, stable bag-making operations.
The film offers excellent flatness with extremely low residual stress. It is fully compatible with dry lamination and solvent-free lamination processes, making it an ideal outer-layer substrate for multilayer flexible packaging structures. Its coefficient of friction remains stable under different processing temperatures, helping ensure smooth operation of high-speed printing and lamination equipment.
High-purity resin combined with specialized surface control technology reduces film haze to ≤2.5%, giving finished packaging a bright, mirror-like gloss. Whether used for complex metallic ink printing or high-saturation solid-color printing, the film can reproduce fine halftone details with clarity and consistency, helping enhance product visibility and brand appeal on retail shelves.
With high tensile strength (MD ≥120 MPa, TD ≥200 MPa), the film provides excellent mechanical protection. As the outermost layer of a multilayer laminated structure, it effectively protects internal barrier materials such as aluminum foil and VMPET, creating a durable external barrier for pharmaceutical and daily chemical products.
Suitable for facial mask pouches, hair and body care product bags, premium wet wipes, and tissue outer packaging. Its high-gloss surface and excellent printability can significantly enhance the visual appeal and brand image of finished packaging.
Suitable for pharmaceutical tablets, capsule pouches, health supplements, and sterilization packaging for medical devices. It provides reliable moisture and water resistance while supporting secure sealing through the single-sided heat-sealable structure.
Used as the outermost printing layer and laminated with AL, VMPET, PE, CPP, or other heat-sealable layer materials for manufacturing various three-side-seal bags and stand-up pouches.
In large-scale B2B international trade, professional packaging and logistics are a continuation of product quality. HUA HENG uses an intelligent, green, and low-carbon logistics system to ensure that every roll of High Strength Heat Sealable BOPP Film remains under comprehensive protection throughout its journey from the Tianjin factory to your overseas facility.
Inside HUA HENG's advanced intelligent manufacturing facility, BYD/Bik electric forklifts are used throughout the material and finished-goods handling process, replacing traditional fuel-powered forklifts. This keeps the film away from oil contamination, exhaust emissions, and fuel residues before packaging and container loading, helping meet the stringent cleanliness requirements of daily chemical, beauty, and pharmaceutical packaging materials.
The first layer completely encloses each film roll with a highly sealed moisture-proof film, with industrial-grade high-capacity desiccants placed inside. Multiple layers of strong water-resistant stretch film are then applied externally to help block marine humidity, salt spray, and dust.
For large-format or high-precision laminated film rolls, HUA HENG uses steel or wooden end plates with a suspended lifting structure. This keeps the film roll elevated rather than in direct contact with the pallet surface, helping prevent film-surface indentations and crystallization damage caused by prolonged pressure or friction.
We understand that ocean transportation can typically take 20–45 days, with container temperatures potentially exceeding 60°C. Therefore, every pallet group is protected with a fully enclosed, high-strength stretch-film wrapping system. Combined with dedicated antistatic and UV-resistant barrier layers, this packaging helps maintain a dry internal microenvironment and reduce the risk of corona-treatment performance degradation caused by condensation and temperature fluctuations.
Our professional international trade supervision team conducts strict checks at the container loading site, including container airtightness, cleanliness, and water leakage inspections. Professional inflatable dunnage bags and securing ropes are used to fill gaps and stabilize the cargo, reducing the risk of collisions caused by movement during ocean transportation.
We fully support pre-shipment factory sampling, packaging inspection, and complete container-loading supervision by internationally recognized inspection organizations such as SGS, Intertek, and Bureau Veritas.
Within 24 hours after shipment, we provide complete commercial invoices, packing lists, bills of lading, and factory quality inspection reports (COA). Our international trade customer service team works closely with shipping carriers to track the ocean freight status in real time, helping customers accurately forecast arrival schedules and achieve seamless production with minimal inventory disruption.
Through a series of energy-saving upgrades—including thermal insulation improvements to the main extrusion filter system, which save approximately 650,000 kWh of electricity annually, waste-heat recovery, which saves around 73,000 m³ of natural gas per year, and intelligent cooling tower control, which achieves 73.4% energy savings—HUA HENG has significantly reduced manufacturing energy consumption and production costs to an exceptionally low level within the industry. This enables HUA HENG to offer not only high-quality BOPP films but also highly competitive factory-direct export pricing.
The company has received the China Packaging Corporation Science and Technology Award and the Packaging Industry Science and Technology Award. HUA HENG also possesses core independent intellectual property rights and industrialization capabilities in areas including gradient control of heat-seal strength in microcrystalline polyolefin films and VOC-free films for paper-plastic lamination.
These accumulated technological capabilities enable HUA HENG to effectively address critical packaging challenges encountered during high-speed production, including ink removal, delamination, insufficient high-temperature resistance, and film sticking to sealing knives, helping customers achieve more stable and efficient packaging operations.
Film sticking to the sealing knife is typically caused by insufficient heat resistance of the non-heat-sealable surface or degradation of the film's slip performance under elevated temperatures. HUA HENG uses a specialized multilayer functional structure to provide the non-heat-sealable surface (printing side) with excellent high-temperature resistance and thermal shear resistance. During the moment when the heated sealing knife closes and cuts the film, the surface resists sticking and stringing, helping ensure smooth operation of high-speed automated packaging lines.
For this printing-grade single-sided heat-sealable BOPP film, the standard MOQ is 1,000 kg. The film rolls are secured using export-grade suspended shafts or paper tube cores, together with moisture-proof film, stretch wrapping film, and fumigation-free pallets for fully enclosed protection. This packaging is suitable for long-distance sea and land transportation.
After order confirmation, the standard lead time is approximately 15–20 days. When safety stock is available at the factory, the delivery time can be shortened to approximately 7–10 days.
Yes. HUA HENG can flexibly adjust the film thickness, corona treatment intensity, and heat-sealing temperature according to your printing process, lamination structure, and packaging machine parameters, providing a customized High Strength Heat Sealable BOPP Film solution for your specific packaging requirements.
