Cellulose Double High Gloss & Clarity Seal Film- Keyful CP-DS

•Derived from renewable wood pulp. Certified for industrial and home composting.

•By adding a small amount of PVDC to optimize moisture and gas barrier properties, it enables simpler and lighter packaging structures, helping to extend and maintain the shelf life of packaged products.It offers high strength, excellent toughness, high transparency, and strong tear resistance.

•Dual-sided heat-sealable capability.

•Resistant to moisture absorption.

Based on renewable wood pulp, airtightness is enhanced by PVDC. It features high transparency and toughness, and double-sided heat sealing and low moisture absorption properties make it suitable for mass customization packaging needs, realizing lightweight and environmentally friendly packaging solutions.

Suitable for the flexible packaging industry: commonly used in single-layer packaging bags for clothing, vegetables, parts, toys, and other single-layer packaging applications.

KEYFUL focus on the research & development, production, manufacturing, and supply of various flexible, environmentally friendly, and biodegradable packaging films, covering BOPP, BOPET, BOPA, PE, and recyclable single-material films, and are committed to meeting the diverse packaging solution needs of the market.

Keyful-CP-DS Cellulose Double High Gloss & Clarity Seal Film is derived from renewable wood pulp and boasts environmentally friendly properties with industrial and home composting certifications. The addition of a small amount of PVDC significantly enhances moisture and gas barriers, supporting simpler, lighter packaging structures and helping to extend and maintain the shelf life of agricultural/food and consumer products. Its high strength, excellent toughness, exceptional transparency, and strong tear resistance result in an extremely clear and transparent finished product appearance.

Double-sided heat sealability and resistance to moisture absorption ensure sealing stability. The film has a thickness of 23±2 microns, a unit weight of 35±2 g/m², a tensile strength MD/TD of 56/28 MN/m², an elongation at break of 18/41%, and an elastic modulus MD/TD of >1200/>600 MN/m². The sealing strength is 1.77 g(f)/25mm (135°C, 0.5 seconds, 69kN/m²). It is suitable for single-layer packaging of clothing, vegetables, parts, toys, etc., providing high-end visual appeal and an environmentally friendly solution.

Applications

•Flexible Packaging Industry: Commonly used for single layer bags for apparel, vegetables, components, toys, and other single-layer packaging applications.

•The gas barrier properties enhanced by PVDC effectively extend the shelf life of food, daily necessities, and other products, reducing waste.

•Double-sided heat-sealing capability simplifies packaging line processes, improving production efficiency and sealing consistency.

    High transparency, strong and low moisture absorption; PVDC’s improved airtightness can reduce the complexity of the packaging structure, making it easy to achieve lightweight packaging.

    The material comes from wood pulp, has industrial and home composting certifications, and meets green supply chain requirements.

    The film itself is mainly high-transparency, and is compatible with various printing and marking processes. Specific optimization is required according to subsequent process parameters.

    Using standard sealing conditions of 135°C and 0.5 seconds as a baseline, the actual conditions need to be adjusted in combination with the packaging line parameters.

    Film thickness, surface gloss and microscopic texture can be negotiated during bulk customization to match customer needs.

    The material is designed to be low moisture absorption, adapts to high humidity environments, and can maintain packaging stability.

    Based on environmentally friendly materials and high light transmittance, bulk customization has economies of scale, and the unit cost is competitive.

    Single-layer packaging for clothing, vegetables, electronic components, toys, etc., and product lines that require high transparency and good protection.
