High Quality Transparent Food Grade Noodle Macaroni Wheat Pasta Bread Packaging Bag

1. Structural features of noodle packaging bags Self-supporting design The back-sealed bag adopts three-side or four-side sealing technology, and the bag body can be displayed independently, which is convenient for shelf display and enhances the visual appeal of the product. Excellent sealing High-frequency heat sealing technology is used to ensure tight sealing, effectively isolate oxygen, moisture and odor, and extend the shelf life of noodles. Window design (optional) Some back-sealed bags are equipped with transparent windows to intuitively display the shape of noodles and enhance consumers' desire to buy.

2. Moisture-proof technology and materials Multi-layer composite material BOPP (biaxially oriented polypropylene): high transparency and good moisture resistance, suitable for ordinary noodle packaging. Aluminum foil composite film (AL): blocks water vapor and oxygen, and the moisture-proof effect is 80 times that of ordinary plastic bags, suitable for high-end or long-term storage noodles. Kraft paper composite layer: enhances puncture resistance, combined with PE/PP inner layer, taking into account moisture resistance and durability. Aluminum-plated film technology The aluminum-plated layer on the surface can reflect light and block moisture, suitable for noodles that need to be stored away from light (such as multi-grain noodles containing natural pigments).

3. Application in noodle packaging Applicable scenarios Noodles/fresh-cut noodles: back-sealed bags with self-sealing zippers are convenient for repeated opening and keep noodles dry. Instant noodles/instant noodles: combined with high-temperature cooking bag technology, it can withstand frying or steam sterilization processes.

4. Advantages and selection suggestions Core advantages Moisture-proof and fresh-keeping: The multi-layer composite structure significantly reduces the water vapor permeability and extends the shelf life by 30%-50%. Environmentally friendly and recyclable: BOPP, kraft paper and other materials meet food-grade safety standards and are partially degradable. Material selection suggestions High humidity areas: aluminum foil composite bags or aluminum-coated film back-sealed bags are preferred. Cost-sensitive: BOPP+PE composite bags are cost-effective and suitable for conventional packaging.

5. Notes Printing process: It is recommended to use gravure printing to ensure ink adhesion and avoid solvent residue affecting moisture resistance. Storage environment: After packaging, it needs to be stored in a dry environment to avoid high temperature and high humidity causing material aging. If specific material parameters or customized solutions are required, further information such as noodle type and shelf life requirements can be provided for accurate recommendation.
