Food Packaging Roll Film is a continuous roll packaging material based on plastic film, primarily used in automated food filling and packaging production lines. It typically consists of a multi-layered composite structure to provide moisture protection, light shielding, oxygen barrier, and prevention of odor penetration. This material possesses excellent heat-sealing properties and mechanical strength, enabling stable operation on high-speed packaging equipment and ensuring a smooth packaging appearance and reliable seal. Its printed layers generally employ gravure printing technology, supporting high-precision multi-color customization to clearly display brand images and nutritional information. Food Packaging Roll Film is often designed with varying thicknesses to meet diverse food packaging needs. As a crucial aspect of food safety, the raw materials used in this product comply with FDA and EU food contact grade standards and are free of BPA, heavy metals, and harmful plasticizers.

1. Superior Barrier Properties:

The Food Packaging Roll Film employs a high-barrier material composite structure, such as PET/AL/PE, PA/PE, or EVOH co-extruded layers, significantly reducing the penetration of oxygen, moisture, and odors. Its oxygen translucency (OTR) can be as low as 0.3 cm³/(m²·24h·0.1MPa), and its water vapor translucency (WVTR) is less than 0.5 g/(m²·24h), effectively delaying food oxidation and moisture loss, maintaining fresh flavor and texture. Even in high humidity, high temperature, or freezing environments, it maintains stable barrier properties, ensuring food quality and safety throughout the entire supply chain.

2. Stable Heat-Sealing Performance:

The inner layer of this packaging film is primarily made of CPP or LDPE, with a wide heat-sealing temperature range (110℃–140℃), making it compatible with various fully automated high-speed packaging equipment. Its heat-sealing strength reaches up to 40 N/15 mm, making it difficult to open or leak, effectively preventing leakage problems during filling or transportation. The heat seal is smooth and neat, ensuring a uniform and aesthetically pleasing packaging appearance. This characteristic is particularly suitable for packaging viscous sauces and liquid foods, improving production efficiency while reducing waste rates.

3. High-Definition Printing Performance:

Zhongxing uses a 10-color high-speed gravure printing press with a printing precision of up to 175 LPI, accurately reproducing complex patterns and gradient colors. The ink layer is durable, scratch-resistant, and heat-sealed, and will not fade due to high temperatures or friction during the packaging process. Both inks and solvents comply with RoHS and REACH environmental standards, are benzene-free and toluene-free, and are suitable for direct contact with food packaging layers. High printing clarity not only helps with brand recognition but also enhances the product's visual appeal on the shelf.

4. Excellent Mechanical Strength:

Food Packaging Roll Film possesses excellent tensile strength and puncture resistance, with a longitudinal tensile strength greater than 120 MPa, a transverse tensile strength greater than 100 MPa, and an elongation of over 150%. Its structural stability ensures smooth operation in automated film rolling systems, preventing breakage or curling. Even in freezing environments as low as -20°C or under high-temperature inflation, it maintains its flexibility and seal integrity, suitable for various packaging line speeds and thickness requirements.

5. Strong Customization and Compatibility:

Zhongxing can customize different material structures, thicknesses (60–150μm), widths (200–1000 mm), and printed patterns according to customer needs. It supports various packaging forms, such as pillow bags, back-seal bags, three-side seal bags, and stand-up pouches, and is compatible with mainstream automated equipment (such as Bosch, Ishida, and ILAPAK). Furthermore, anti-fog layers, anti-slip layers, or easy-tear designs can be added to enhance packaging functionality and consumer experience.

1. Snack Food Packaging:

Food Packaging Roll Film is widely used in automated packaging of products such as potato chips, nuts, candies, and biscuits. Its high-barrier layer effectively prevents oxidation and moisture absorption, maintaining the crispness and aroma of the food. High-definition printing showcases brand logos and product image, attracting consumer attention. The material is lightweight, environmentally friendly, and easy to seal, helping to extend shelf life and reduce transportation costs.

2. Condiment and Liquid Food Packaging:

Suitable for liquid packaging scenarios such as ketchup, salad dressing, chili sauce, honey, and jam. The film material has excellent heat-sealing and leak-proof properties, and can withstand filling pressure and external extrusion. It maintains stable strength after high-temperature sterilization, without interlayer separation or bubbling, ensuring food hygiene and safety.

3. Frozen and Convenience Food Packaging:

Food Packaging Roll Film is widely used in packaging frozen dumplings, meat products, vegetables, and fruits. The material can withstand freezing storage environments down to -30°C without cracking at low temperatures, maintaining its seal and puncture resistance during cold chain transportation. The printed layer is moisture-proof and scratch-resistant, and will not fade even after exposure to condensation, making it suitable for frozen shelf display.

4. Packaging for Coffee Powder and Dry Powders:

Suitable for dry goods such as coffee powder, milk powder, protein powder, and flavoring powder. Utilizing an EVOH oxygen barrier layer structure, it effectively prevents aroma evaporation and moisture ingress, keeping the product dry and flavorful. It supports a one-way vent valve design to prevent the bag from bursting due to gas expansion. Printing can achieve a metallic sheen or matte finish, enhancing the premium brand image.
