Nylon Transparent Vacuum Food Packaging Bag

 

This product is a food-grade PA+PE nylon composite transparent vacuum bag, suitable for vacuum packaging of the vast majority of cooked foods, fresh produce, dried goods, pickled and preserved foods, grains, meat products, and other food items. It integrates high transparency, high barrier properties, strong toughness, low-temperature resistance, and stable sealing performance. It serves as a versatile vacuum packaging solution for food processing plants, supermarkets, e-commerce platforms, catering services, and export trade, compatible with various vacuum packaging machines. With exceptional versatility and broad applicability, it meets extensive industrial requirements.

I. Core Materials and Safety Standards

Utilizing a food-grade nylon (PA) + polyethylene (PE) multi-layer co-extruded composite structure, this product is manufactured from virgin raw materials and strictly complies with national food contact safety standards. It is odor-free, free of plasticizers, heavy metals, and fluorescent agents, enabling direct contact with raw and cooked foods for safe and reliable use. The nylon layer provides strength, toughness, and high barrier properties, while the PE layer ensures excellent heat sealing performance. The material is flexible and non-brittle with superior sealing capabilities, making it suitable for various applications including ambient temperature storage, refrigeration, and freezing scenarios.

High transparency and luminosity for excellent display performance

The bag has high transparency, low haze, and a smooth, glossy surface. After vacuum sealing, it clearly displays the natural color, texture, and morphology of the food products, making their visual appeal immediately apparent. This enhances shelf presentation, online photography, and gift box packaging quality, allowing the freshness of ingredients to be readily discernible and thereby boosting purchasing intent and brand image.

Nylon is strong, tough, and puncture-resistant, with low susceptibility to damage.

 

Nylon material exhibits outstanding toughness, with excellent tensile strength, wear resistance, and high puncture resistance. It is suitable for packaging bone-in meats, granular grains, hard dried goods, and cooked foods with tendons. During vacuum packaging, it is less prone to punctures, edge cracking, or perforation, significantly reducing damage rates during production, transportation, and storage. Its durability far surpasses that of conventional single-layer plastic bags.

High barrier properties for oxygen and moisture resistance, extending shelf life

 

It effectively blocks the intrusion of external oxygen, moisture, odors, dust, and bacteria, delaying food oxidation, spoilage, mold growth, flavor transfer, drying, and discoloration. After vacuum sealing, it locks freshness, moisture, flavor, and color, resulting in more aromatic cooked foods, fresher raw products, non-rehydrated dried goods, and pest-free grains, significantly extending shelf life and storage duration.

Exceptional sealing performance with no air leakage or bag rupture

The heat sealing performance is stable, ensuring robust and uniform sealing. After vacuum treatment, there is no detachment, air leakage, rebound, or bag rupture, demonstrating resistance to long-distance courier transportation shocks, cold storage stacking compression, and low-temperature freezing expansion. The sealing consistency is excellent, compatible with various commercial single-chamber, double-chamber, and continuous vacuum packaging machines, with smooth installation and high efficiency.

Resistant to low temperatures without brittleness, suitable for freezing applications

It can withstand long-term storage at-18°C low-temperature freezing without hardening, brittleness, deformation, or delamination of the bag body. Suitable for long-term cold storage and cold chain logistics of fresh meat, frozen ingredients, and ready-to-eat meals, and is compatible with ambient temperature, refrigerated, and frozen temperature zones.

Clean, tidy, and easy to print with flexible customization

The bag body is clean, non-oily, non-sour, and odor-resistant. It supports color printing, monochrome printing, matte/gloss finishes, LOGO printing, product information printing, nutrition labeling, traceability codes, and customized gift box patterns. Various structures can be achieved, including three-side sealing, flat opening, thickening, and enlargement, to meet comprehensive needs for small packaging, large packaging, and gift packaging.
