【Core Highlights】

●  Zero-Dead-Corner Fit: Expertly engineered with 5 heat sealing lines to form a perfect square bottom, ensuring the bag fits     closely to the inner walls of cardboard boxes.

●  Optimized Space Utilization: The structured bottom design eliminates wasted space and prevents content entrapment in "dead     corners" during filling and pouring.

● Versatile Material Lining: Suitably used as high-performance inner bags for both food ingredients and industrial materials,     providing a clean and secure environment.

●  Robust Seal Integrity: Advanced multi-line sealing technology ensures exceptional leak resistance and structural stability under     heavy loads. 

【Technical & Design Benefits】

● Box-Matched Geometry: Designed to mirror the shape of standard shipping cartons, reducing stress on the plastic film and     preventing accidental punctures or tears.

● Superior Barrier Protection: Acts as a reliable shield against moisture, dust, and contaminants, preserving the purity of the     internal food or raw materials.

● Smooth Content Discharge: The flat-bottom structure ensures that powders, granules, or liquids flow out completely without     getting stuck in folded seams.

●  High Tensile Strength: Manufactured from premium resins to withstand the pressure of bulk-filled contents during stackable          storage.

【Common Application Scenarios】

●  Bulk Food Ingredients: The ideal inner liner for large boxes of flour, sugar, spices, or frozen fruits, maintaining hygiene and     freshness.

● Chemical & Industrial Raw Materials: Safely contains resins, pigments, or chemical powders, preventing leakage and     environmental exposure.

●  Pet Food & Agriculture: Used as a protective barrier for bulk animal feed, seeds, or fertilizers in corrugated box packaging.

●  Liquids & Semi-Liquids: Provides a secure, box-compatible lining for oils, sauces, or industrial pastes.
