Material Performance
BOPET12 provides high surface stiffness and excellent printing adaptability for vivid, high-definition graphics.
AL7 aluminum foil layer offers superior oxygen & moisture barrier, blocking light penetration to prevent active ingredients from oxidation and degradation.
BOPA15 nylon layer greatly improves puncture resistance and bending durability, resisting pinholes during retort processing and transportation.
LCPP70 retort cast polypropylene serves as heat-sealing layer, stable under 121°C retort condition, no melting, delamination or leakage.
Core Advantages
121°C high-temperature retort capable. Suitable for commercial sterile retort sterilization, extend shelf life without preservatives.
Contoured bottle-shaped die-cut design. Unique silhouette stands out among regular pouches on retail shelf, attracting consumer attention.
Multi-layer high-barrier composite. Aluminum foil blocks oxygen, moisture and UV light, protecting protein and heat-sensitive nutritional components.
Strong interlayer lamination. Even after high temperature cooking, the film layers stay tightly bonded. No delamination, bubbling or edge peeling.
Good drop & puncture resistance. Nylon layer enhances physical strength, suitable for filling, boxing, stacking and long-distance shipment.
Stand-up design. The pouch can stand steadily on shelves, convenient for filling, packing and end-user consumption.
Customization Options
- Make your packaging stand out with a fully customized special-shaped retort pouch. We support custom dimensions, unique contour designs, vibrant gravure printing, matte or glossy finishes, laser easy-tear features, batch coding and anti-counterfeit elements. Whether you need higher barrier, stronger heat seal or a specific shelf-life target, we can tailor the film structure to your liquid product and retort process.
Application Scenarios
Designed for retortable liquid packaging, this bottle-shaped stand-up pouch is ideal for sports nutrition, protein drinks, oral liquids, functional purees and special dietary foods. It combines the stability of a stand-up pouch with the visual attention of a contoured bottle-like package, helping your product stand out on retail shelves while protecting sensitive ingredients from moisture, oxygen and light.
Production & Quality Control
- Every pouch is manufactured in a controlled clean production environment. We manage the complete process from printing and lamination to pouch making, contour cutting and final inspection. Before delivery, each batch undergoes retort simulation, seal integrity testing, leakage checking, peel strength analysis and barrier performance verification to ensure reliable performance under high-temperature sterilization.
FAQ
Q: Can this pouch hold acidic liquid or protein-rich liquid for retort processing?
A:Yes. LCPP70 retort grade inner layer and stable composite structure suit most protein drinks and weakly acidic liquid. We suggest compatibility test with your actual formula before mass production.
Q: Will the contour die-cut shape affect sealing strength during retort?
A: The die-cut contour avoids sharp corner at sealing edge. Our slicing process optimizes the corner transition. After 121℃ retort, the sealing edge maintains reliable strength, no leakage risk.
Q: Is it possible to add laser easy tear on this special-shaped pouch?
A:Yes, laser easy tear line can be added at designated position. We will adjust laser depth carefully to avoid piercing the whole film and impacting barrier property.
Q: What is the minimum order quantity for custom gravure printing?
A: MOQ depends on pouch size and printing colors. Contact our sales team for detailed quotation and lead time.
Q: Are the bags food‑contact safe?
A: All raw materials are food‑grade, comply with common international food contact requirements.
