1. Product Overview: A Safe Storage Solution for Food-Grade Three-Side Seal Moisture-Proof Plastic Bags

Food-grade three-side seal moisture-proof plastic bags are high-standard packaging products specifically designed for food storage and packaging. Made of food-grade plastic materials and featuring a three-side heat-sealed structure, they possess excellent moisture-proof, sealing, and hygienic properties, effectively protecting food from air, moisture, dust, and external contamination, ensuring food remains clean, safe, and fresh during transportation, display, and storage.

2. Food-Grade Materials: Safe and Odorless Healthy Packaging


Food contact safety is one of the core advantages of this packaging bag. The bag body uses food-grade PE, PET, or composite film materials, free of harmful substances, odorless, and with no migration risk, suitable for direct contact with various foods. The material surface is smooth and clean, oil- and water-resistant, and will not chemically react with food, ensuring greater consumer peace of mind.


3. Three-Side Seal Structure: Stable and Durable Sealing Protection


The three-side seal design forms a stable structure through high-temperature heat sealing of three sides, possessing the following characteristics:

Strong Sealing: Effectively prevents air from entering, reducing oxidation and spoilage.

Smooth Structure: The bag is evenly stressed, making it less prone to breakage or leaks.

Suitable for Various Thicknesses: Different film thicknesses can be selected according to food type, enhancing durability.

This structure is particularly suitable for food packaging scenarios requiring high sealing and hygiene standards.


4. Moisture-proof Performance: Keeps food dry and fresh. The bag uses high-barrier moisture-proof materials, effectively preventing moisture penetration, keeping food dry, and extending shelf life.


Moisture-proof performance is suitable for:

Dried goods (nuts, beans, grains)

Baked goods (biscuits, pastries)

Powders (seasoning powder, milk powder)

Frozen foods (meat, seafood)

Whether for home storage or commercial packaging, it maintains the original flavor and taste of food.


5. Hygienic and Clean: A reliable choice for safe storage. The bag production process uses a dust-free environment and food-grade processes to ensure the packaging bag surface is clean and uncontaminated.


Its advantages include: dustproof, oil-proof, and odor-proof; suitable for direct contact with food; and can be stored in refrigerated, frozen, and ambient temperatures. This makes it an ideal choice for catering, food processing plants, retailers, and home users.
