Single Sided Heat Sealable BOPP Film is a functional packaging film designed for high-speed automated packaging. It features an asymmetric structure, with a specially formulated heat-sealable layer on one side and a smooth printable surface on the other side, suitable for both gravure and flexographic printing.
The film typically offers a heat-sealing temperature range of 118°C–140°C, a heat-seal strength of ≥2.0 N/15mm, and low haze of ≤4%, helping high-speed packaging lines achieve stable sealing, leak prevention, and an attractive package appearance.
Thicknesses from 15μm to 50μm and widths from 400mm to 2500mm can be customized. Options include corona treatment on the non-heat-sealable side, low-temperature heat-sealing formulation adjustments, and customized roll diameters and core sizes to accommodate different packaging equipment and product requirements.
Single Sided Heat Sealable BOPP Film typically provides a heat-sealing temperature range of 118°C–140°C, with heat-seal strength reaching ≥2.0 N/15mm.
Its stable heat-sealing performance helps packaging machines form secure seals during high-speed automated production, reducing the risk of defective seals and leakage. This makes it suitable for packaging lines where production efficiency and sealing reliability are critical.
The film provides high gloss and low haze of ≤4%, allowing packaged contents and product details to remain clearly visible.
For food, cosmetics, and consumer product packaging, high transparency enhances shelf presentation while giving the finished package a clean and well-defined appearance.
The film helps reduce the impact of moisture, oxygen, and external contaminants on packaged contents, providing additional protection for applications requiring barrier performance.
For food and consumer product packaging, the appropriate material structure can be selected and tested according to the specific product and packaging requirements.
The non-heat-sealable side is designed for compatibility with gravure and flexographic printing, allowing brand graphics, product information, and other packaging visuals to be printed clearly.
Corona treatment can also be provided on the non-heat-sealable side according to customer requirements to further improve ink adhesion.
The BOPP substrate provides good tensile strength and puncture resistance, allowing the film to withstand mechanical stress during packaging, handling, transportation, and storage.
This helps reduce the risk of film tearing and damage throughout the packaging and logistics process.
The film provides anti-static properties that can help reduce dust attraction and minimize machine stoppages or feeding issues caused by static electricity during automated packaging operations.
Single Sided Heat Sealable BOPP Film is manufactured using a co-extrusion production line. Strict process controls help maintain consistent film thickness, stable product performance, and reliable batch-to-batch quality.
The film is manufactured using 100% virgin polypropylene (PP) resin. It is non-toxic and recyclable, with product performance subject to strict quality testing.
For food packaging applications, HUA HENG can provide relevant third-party testing reports covering applicable food safety regulations and standards, supporting customers during compliance and supplier qualification reviews.
Before placing a bulk order, we recommend that customers conduct sample testing together with their actual packaging equipment and products. Key evaluation factors include:
● Heat-sealing temperature window
● Heat-seal strength
● Packaging machine speed
● Seal integrity
● Film transparency and haze
● Print adhesion
This testing process helps confirm compatibility before large-scale procurement.

The film can balance package appearance, sealing performance, and mechanical protection requirements during handling and transportation.
German Bruckner BOPP production lines and advanced co-extrusion technology help ensure consistent film thickness and stable quality.
Manufactured with 100% virgin polypropylene resin, the film is non-toxic and recyclable.
As a direct manufacturer, HUA HENG provides competitive factory pricing, short lead times, and flexible MOQ options.
Strict production controls and product testing help ensure consistent performance and compliance with packaging industry requirements.
The standard MOQ is typically 1,000 kg or 3,000 m². Flexible trial-order options may be available for new customers testing the market. The final MOQ can be negotiated according to film thickness, width, and specific order requirements.
HUA HENG supports customization of 15μm–50μm thickness and 400mm–2500mm width. Options also include corona treatment on the non-heat-sealable side, low-temperature heat-sealing formulation adjustments, roll diameter, and core size customization.
Yes. The film can be used for food packaging applications and is manufactured with 100% virgin polypropylene (PP) resin.
For food packaging projects, relevant third-party testing reports covering applicable food safety regulations and standards can be provided according to customer requirements to support compliance reviews.
For standard specifications, the typical lead time is 7–10 working days. Special customized orders generally require 10–15 working days.
The actual lead time depends on the order specifications and quantity and can be clearly agreed upon in the sales contract.
Yes. Customers can request a standard test roll for machine testing before bulk procurement.
The standard test roll size is 350mm × 50m, which can be used to evaluate heat-sealing performance and printing results.
The film should be stored in a cool, dry environment away from direct sunlight.
Under proper storage conditions, unopened film can be stored for several years. To maintain optimal heat-seal strength and printing performance, it is recommended to use the functional film within 6 months after delivery.
