Can your packaging bags be used for microwave heating or high-temperature sterilization?

We supply high-temp composite packs for retort/microwave use. Standard PE & foil bags fail high heat, but our custom retort pouches withstand sterilization for meat, ready meals & canned alternatives. Share your exact temp specs upfront for matched heat-resistant materials.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier offering 3D software design, R&D-supported customization, ODM, and OEM services. It holds an ISO9001:2015 certificate and reports documented quality-control, traceability, complaint-handling, supplier-management, and corrective-action procedures. Production evidence includes more than 10 production lines, solventless compounding and printing equipment, 50 quality-control staff, and exports to Europe and North America. The supplier supports extensive packaging customization and reports new-product development during the past year. However, no SDK is available, and the provided information does not sufficiently establish financial credibility, after-sales service performance, or specific customer cases.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated product scope covers plastic packaging, printed plastic products, film rolls, laminated packaging, food, industrial and medical packaging bags, shrink labels, gravure printing, and custom packaging services; it also operates from a stated factory location and has more than 10 production lines.

CertificationsThe supplier reports holding an ISO9001:2015 certificate, and the same certification is listed under sustainable development management. The evidence confirms certification holding, although no separate certification details or validity period are provided.

After-Sales capabilityThe supplier has a clear customer-complaint procedure with followed records, written supplier-service assessment procedures, an approved-supplier list, and documented corrective and preventive action procedures. These records support structured service handling, but do not directly demonstrate after-sales response outcomes or customer satisfaction.

R&D capabilityThe supplier provides 3D software design, has R&D-supported customization, reports new products within the past year, and offers ODM and OEM services. It explicitly has no available SDK, so its innovation capability is supported for product and design development but not for SDK availability.

Production capacityThe supplier offers a broad range of plastic and printed packaging products, operates more than 10 production lines, and lists solventless compounding and printing machines. It also reports 50 quality-control staff and export markets in Europe and North America, providing explicit evidence of established production capacity.

Product Q&A

Q:Do you provide free samples? What's the sample cost and delivery time?

Free blank & similar finished samples; you cover shipping cost. Custom printed logo samples incur minor plate & sample fees, fully refundable on bulk orders. Samples take 3-7 working days, delivery 3-7 days based on your country.

Q:Are your plastic packaging materials environmentally friendly and food-safe?

All our raw materials meet international food contact safety standards and environmental protection requirements. We can provide third-party MIC test reports, food-grade certification documents and environmental inspection certificates upon your request. We also produce biodegradable plastic bags and compostable kraft paper packaging to cater to customers with eco-friendly packaging demands, effectively reducing plastic pollution.

Q:Can you produce special functional packaging bags, such as moisture-proof, oxygen-proof and heat-sealable bags?

Yes, we are capable of manufacturing multi-functional composite packaging bags. Our aluminum foil bags, vacuum bags and thickened composite roll films have excellent moisture-proof, light-shielding, oxygen-isolating and fresh-keeping effects, which are widely used for food, nuts, snacks, cosmetics and electronic accessories. We can also add special functions like anti-static, oil-proof and high-temperature resistance according to your product storage requirements.

Q:Is it possible to adjust the bag thickness and material structure according to my product weight?

Of course. Different products have different weight, storage and packaging demands. For heavy-weight products such as grains and pet food, we will recommend thickened multi-layer composite materials and flat bottom stand-up bags with strong load-bearing capacity. For lightweight cosmetics or small snacks, we can use thin, lightweight BOPP or PE materials to cut your packaging cost. Share product net weight, our team recommends optimal material thickness & structure.

Q:Can I get custom printed logos and patterns on the packaging bags?

We offer full custom printing: logos, info, labels, QR codes, patterns & slogans on all bags. Gravure & digital printing available. Send AI/PDF/CDR files for direct plate making; free design support if no artwork.
