High hot tack Low-Temperature Heat-Sealable film is a functional BOPP film designed for flexible packaging. Featuring a specialized heat-seal layer, it enables reliable sealing under lower heat-sealing conditions. For clients in sectors such as food, personal care, pharmaceuticals, and consumer goods, the value of low-temperature heat sealing extends beyond merely "lower temperatures"; more importantly, it helps packaging enterprises achieve more stable seals, better production compatibility, and higher efficiency in actual operations.
Traditional heat-sealing processes requiring high temperatures can place greater demands on packaging materials, printed layers, or production equipment. The design focus of this high hot tack low temperature heat sealable film is to enable the heat-seal layer to form an effective seal more easily at lower temperatures. For continuous automated packaging lines, this means enterprises can optimize process parameters—such as heat-sealing temperature, pressure, and dwell time—based on specific equipment and product requirements, making it an ideal choice for companies prioritizing production efficiency and seal stability.
For packaging clients, heat sealing is not simply about "getting it sealed." The seal must remain stable throughout production, transportation, warehousing, and consumer use. High-tack heat-sealing performance enhances seal reliability, making it particularly suitable for applications requiring high packaging integrity. However, the final sealing performance in actual use requires a comprehensive assessment involving packaging equipment, heat-sealing temperature, pressure, dwell time, film thickness, packaging structure, and the product being packaged.
Huaheng offers sample testing and assists clients with on-machine verification and process adaptation.
Huaheng specializes in the R&D and production of BOPP films, with products widely used in packaging for food, pharmaceuticals, consumer goods, apparel, adhesive tapes, tobacco, and books. Depending on the packaging structure, the BOPP film can be used as a single-layer package or in combination with other materials. Therefore, when selecting high-tack, low-temperature heat-sealable film, the choice should be based on the customer's existing packaging structure, equipment, and end product, rather than simply relying on a fixed set of parameters.
Our company currently operates two German Brückner BOPP film production lines utilizing the biaxial orientation process. Each line has an annual capacity of 30,000 metric tons, resulting in a total annual capacity of 60,000 metric tons. The lines can reach speeds of up to 450 meters per minute and produce films ranging from 10 to 60 μm in thickness; they are also equipped with downstream processing facilities for slitting, inspection, and packaging. For overseas B2B clients, this means we offer not only the products themselves but also the manufacturing infrastructure necessary for consistent production and reliable order fulfillment.
On high-speed packaging lines, the stability of the heat-sealing process directly impacts production efficiency. High hot tack low temperature heat sealable film serves as a functional heat-sealing material for these applications and can be matched to specific equipment processes.
Food packaging, snack packaging, baked goods packaging, daily commodity packaging, and other automated flexible packaging applications.
For certain packaging structures where the production process is sensitive to heat-sealing temperatures, high hot tack low temperature heat sealable film is an ideal choice. In practice, the appropriate heat-sealing temperature window should be determined through sample testing rather than setting equipment parameters based solely on the product name.
The high-tack heat-seal design prioritizes seal reliability. For food, personal care products, and other items requiring package integrity, the appropriate heat-sealable film can be selected based on the specific packaging structure and equipment conditions.
High hot tack Low-Temperature Heat-Sealable films are highly sensitive to ambient temperature and humidity. To prevent moisture damage, edge curling, or deformation caused by temperature fluctuations during ocean shipping and container transport, every roll of Huaheng film undergoes rigorous five-layer protective packaging:
The film surface is wrapped in high-strength bubble wrap to absorb vibrations and impact forces during transit.
A heavy-duty plastic bag provides a fully sealed vacuum enclosure, locking in the internal environment and blocking out the high-salinity, high-humidity air encountered during ocean voyages.
Specially designed, high-rigidity plastic disc clamps are fitted to both ends of the roll core, effectively preventing telescoping (shifting of layers) or edge damage during stacking or handling.
We use heavy-duty, fumigation-free composite pallets that meet international export standards (supporting horizontal or suspended loading for 3-inch or 6-inch cores), secured with a cross-pattern strapping system using high-strength plastic-steel bands.
The entire pallet is wrapped in multiple layers of industrial stretch film, ensuring the load remains rock-solid and stable even amidst the rough seas and turbulence of container transport.
Huaheng has established a comprehensive quality control system covering the entire process from raw materials to finished products.
Our in-house laboratory is equipped to perform testing and quality control at every stage: raw materials → semi-finished products → finished products.
For B2B clients, this end-to-end control is far more important than simply showing a "product photo," as the film must ultimately perform reliably on the client's production line. We hold ISO Quality Management System and ISO Environmental Management System certifications, possess 56 patents (including invention and utility model patents), and have led or participated in the drafting of 14 national, industry, and group standards.
Depending on the specific packaging structure required by the client, these products can be applied to sectors such as food, personal care, pharmaceuticals, and household goods. Huaheng’s BOPP products currently serve a wide range of industries, including food, pharmaceuticals, personal care, tobacco, and adhesive tapes.
No.
The actual heat-sealing temperature must be determined through testing based on the specific film grade and thickness, packaging equipment, sealing pressure, sealing duration, and packaging structure. Therefore, actual production parameters should be based on the product’s Technical Data Sheet (TDS) and the results of the client's on-machine testing.
Yes.
Huaheng supports the customization of specifications—such as thickness, width, and heat-sealing temperature—to meet client requirements.
Yes.
We provides samples for testing and can assist clients with on-machine validation and process optimization.
We are a manufacturer. We operate our own BOPP film production base in the Nangang Industrial Zone of the Tianjin Economic-Technological Development Area (TEDA), equipped with two German Brückner BOPP production lines and a total annual production capacity of 60,000 tons.
