✅ Stand-up: Self-supporting after filling for nice display
Low Temperature Adaptability
Standard paper-plastic laminates often suffer glue failure and delamination under refrigeration. We adopt low-temperature adhesive for cold chain applications. The laminate retains good toughness with minimal shrinkage or deformation under temperature fluctuation, suitable for cold-chain production, warehousing, transport and retail display.
Leakage & Stain Resistance Technology
Dual protection designed for oily, leak-prone contents such as sauces and wet food. Modified PE inner layer blocks grease, moisture and protein penetration. Precision automatic heat sealing delivers solid seams free of pinholes or weak seals. Combined material and process protection minimizes leakage and staining.
Humanized Opening Design
Equipped with PET precision easy-tear notch. Tool-free manual opening with smooth cut edges, no burrs or stringing. Notch position and dimensions are customizable to match packaging layout and user habits.
Sealing & Freshness Preservation System
Food-grade interlocking zipper with smooth operation and secure closure. Before opening, the 3-layer laminate and sealed edges block oxygen and moisture. After opening, repeated sealing slows oxidation, moisture uptake and flavour transfer, extending shelf life for multi-use products.
Display & Brand Advantages
Matte textured paper stands out from common aluminized or transparent plastic packaging. The stand-up base keeps pouches upright for attractive presentation on retail shelves, online stores and exhibition booths. It supports high-quality printing for logos and graphics to build brand differentiation.
Printing Technology Compatibility
The BOPET print layer offers stable ink adhesion and accurate colour reproduction. Flexo and spot colour printing are available for full-surface prints, fine lines and gradients. The printed surface resists scratches during storage and shipment to keep artwork vibrant.
Main Application Scenarios
- Pet food: Cold wet food, paste treats, liquid supplements, chilled pet sauces;
- Food: Refrigerated condiments, concentrated broths, semi-fluid chilled food;
- Beauty & personal care: Cold-stored skincare essences, paste formulations;

Full Customization Service
One-stop customization service. Customizable options include pouch size, artwork, logo, spot colours, notch specification, zipper style and seal design. Sample testing, small trial orders and mass production available. We adjust processes according to filling equipment and product features to deliver tailored packaging solutions.
Strict Quality Control
- Full-process quality inspection from raw material receiving to shipment. Each batch undergoes 5 key tests: low-temperature aging, seal strength, peel strength, leakage test and oil resistance. 100% visual inspection for pinholes, colour deviation and damage. Compliant with food contact standards. Test reports available upon request.
FAQ
Q: Is this paper pouch suitable for long-term packaging of refrigerated liquid and paste products?
A:Yes. Developed for cold liquid and paste. The low-temp lamination plus leak-proof modified inner layer prevents delamination, bubbling, oil seepage and liquid leakage during refrigeration, suitable for wet food and sauces.
Q: Will the paper-film laminate peel or bubble under low temperature?
A:No. Special low-temperature adhesive maintains strong bonding at 0–10℃ cold chain, no delamination or bubbling. More stable than standard paper-plastic pouches.
Q: Can we modify the position and size of the easy-tear notch for our design?
A:Fully customizable. Notch position, dimension and angle can be adjusted to fit your artwork and usage preference.
Q:Is it oil-resistant for oily wet food and sauces?
A: It delivers good oil resistance. Modified PE inner layer resists contamination. No penetration upon prolonged contact with oily sauces and pet wet food, great for high-oil cold products.
Q: What printing options are available for custom premium graphics?
A: Spot colour and gravure printing supported. Fine text, gradients and full-surface artwork are achievable with accurate colour rendering for premium branding.
