3. Core Advantages：Three-Side Seal Pouch for 1kg Fish Food

3.1 Airtight Three-Side Heat Sealing for Maximum Freshness Retention

We adopt advanced three-side heat-sealing technology to create a hermetic seal, effectively blocking oxygen, moisture and light. The aluminum foil lamination enhances oxidation resistance and UV protection, slowing down vitamin degradation in fish food. The reusable zipper closure maintains tightness after repeated openings, resolving the freshness issue of partially used 1kg fish food. All sealing processes undergo rigorous testing with professional equipment to ensure zero leakage during transportation and storage.

3.2 Food-Grade Laminated Materials & Safety Certifications

Our Three-Side Seal Pouches are crafted from food-grade PET/AL/PE composite materials, which are non-toxic, odorless and free of harmful substances. The materials meet international food contact safety standards and hold ISO 9001 certification superscript:3:. Ideal for packaging oily and acidic fish food, they offer excellent oil resistance and corrosion resistance. Additionally, the materials are low-temperature tolerant, adapting to various storage environments to ensure product safety and stability.

6.FAQs

Q1: Is the window material of the flat bottom bags resistant to high and low temperatures, and will it fog up?

A1: The window material we use is high-performance BOPP, which exhibits excellent resistance to both high and low temperatures (adapting to -20℃ to 80℃ environments). For scenarios with temperature fluctuations, we offer an optional anti-fog coating that prevents condensation and fogging, ensuring the window remains clear for product display at all times.

Q2: How long can the moisture-proof performance of the bags last for bulk storage?

A2: The moisture-proof performance depends on the selected material. For standard BOPP/PE composite bags, the moisture-proof effect can maintain product freshness for 6–12 months under normal storage conditions. For high-barrier aluminum foil composite bags, the shelf life can be extended to 12–24 months, fully meeting the long-term bulk storage needs of fish food.

Q3: Can the flat bottom bags be integrated with our existing automatic filling production lines?

A3: Yes. Our flat bottom bags are designed with compatibility in mind, matching the specifications of mainstream automatic filling equipment in the fish food industry. We can also adjust the bag's opening size and bottom structure according to your specific filling machine parameters to ensure seamless integration and high-efficiency production.

Q4: What is the MOQ for bulk customization, and can the delivery time be shortened for urgent large orders?

A4: Our standard MOQ for customized flat bottom bags with windows is 10,000 pieces. For urgent large orders, we can prioritize production resources to shorten the delivery time—typically reducing it by 3–5 days based on the order quantity and customization complexity. Please contact our sales team in advance to confirm the feasibility.

Q5: What payment methods and international trade terms do you support?

A5: We support flexible payment methods for large orders, including T/T (Telegraphic Transfer), L/C (Letter of Credit), and D/P (Document against Payment). In terms of international trade, we offer FOB, CIF, and EXW terms to accommodate your logistics and customs clearance needs, ensuring smooth cross-border transactions.
