Our series includes Flat Bottom Powder Pouches, Flat Bottom Soup Pouches, and Flat Bottom Seafood Packaging Bags engineered for industrial filling, retail display, and long-distance shipping. All structures support OEM printed flat bottom packaging pouches with premium 10-color printing to strengthen your brand image.
As professional Retortable flat bottom food pouches, they withstand 121°C autoclave sterilization while maintaining shape and seal integrity. Our Flat bottom pouches for powder packing, Flat bottom pouches for soup packaging, and Seafood Packaging Bags solve leakage, puncture, and caking issues effectively.
A flat bottom pouch, also known as a box pouch, is an eight-side sealed flexible packaging bag with a fully flat base. Different from ordinary stand-up pouches, this structure delivers stronger stereoscopic shape, vertical stability, and larger loading capacity. These flat bottom pouches for powder packing, flat bottom pouches for soup packaging and flat bottom pouches for seafood are widely popular in industrial food packaging for their airtight sealing and high barrier performance.
● Specially designed as flat bottom pouches for powder packing, these bags maintain a neat rectangular shape without bulging or collapsing. The anti-static inner film prevents fine powder from sticking to the sealing area. Perfect for protein powder, spice powder, flour, and nutritional supplements. Aluminum barrier structures effectively avoid moisture absorption and powder caking.
● Our heavy-duty Flat Bottom Soup Pouches are professional retortable clear flat bottom food pouches that can withstand 121°C high-temperature sterilization. Reinforced base and side gusset seals resist liquid pressure and prevent bursting during heating or freezing. Ideal packaging for broth, thick soup, sauces, and ready-to-heat instant meals.
● Frozen shrimp, crab legs, and fish can have sharp edges. Our frozen seafood packaging bags incorporate a BOPA (Nylon) layer to provide extreme puncture resistance, ensuring the vacuum seal remains intact during transit and deep-freeze storage.
● We utilize high-metallocene PE (blown in-house) for the sealant layer. This provides superior "Hot-Tack" strength, ensuring that even if the seal area is contaminated by fine powder or oily soup, the bond remains hermetic and airtight.
● Aluminum Foil: For absolute oxygen and light block, ideal for flat bottom pouches for powder packing.
●Transparent High-Barrier: Clear visibility for flat bottom pouches for soup packaging and flat bottom pouches for seafood.
● Our side-gusset seals are reinforced to withstand the expansion of liquids during freezing or the internal pressure of compressed powders.
● Perfect for multi-use Flat bottom powders bag, allowing consumers to reseal and maintain product freshness.
● We can add reinforced punch-out handles for bulk 2kg-5kg seafood bag or powder packs, making them easy for customers to carry.
● Ensures a straight, clean opening for liquid soups bag to prevent messy spills.
Clear Flat Bottom Seafood Packaging Bags are built for the harshest conditions – sharp shrimp shells, crab legs, and fish fins. The integrated BOPA (Nylon) layer provides extreme puncture resistance, while the structure remains flexible and crack-free at -40°C, ensuring vacuum seals stay intact through long冷链 logistics and deep-freeze storage.
For dry products, Clear Flat Bottom Powder Pouches solve the "toppling" problem. Protein powders, flour, and spice blends stay perfectly upright on shelves thanks to the square-bottom design. Anti-static inner films and dust-proof zippers prevent fine particles from contaminating the seal area – even after repeated consumer opening.
When it comes to liquids, Flat Bottom Soup Pouches deliver zero-leak assurance. Reinforced bottom seals and high hot-tack strength handle hot-fill, retort sterilization (up to 121°C), and frozen storage without bursting. Laser scoring ensures a clean, straight tear – no messy spills when consumers open the pouch.
From frozen raw shrimp and battered fish fillets to bone broth, curry sauces, and collagen powder – Meiji's flat bottom pouches are verified across 20+ food categories globally.
We don't just laminate; we blow the core sealant films ourselves. This allows us to customize the film's "slip" for high-speed powder filling lines and its "impact resistance" for heavy frozen seafood applications.
Every batch of our liquid and powder pouches undergoes vacuum chamber leak tests and 1.5-meter drop tests to ensure they survive the rigors of global e-commerce shipping.
