Yes. We offer custom dieline engineering for boxes, flexo printing to 8 colors on mailers and rotogravure to 10 colors on pouches, Pantone color management with retained drawdowns, and private-label packing. Custom dielines start from 5,000 pcs (boxes) and custom prints from 10,000 pcs, with a pre-production sample approved by you before mass production.

Yes — plain stock samples are free; you only pay the courier charge (we use your DHL/FedEx account if available). Custom-printed pre-production samples are charged at cost and refunded against the first order. Sample lead time is 3–7 days depending on complexity.

Stocked items: 12–18 days after deposit. Custom prints: 18–25 days including plate/dieline making and sample approval. We ship FOB Shenzhen or Guangzhou, and can quote CIF/DDP for major ports. A 40HQ container loads 70+ CBM of flat-packed packaging — paper bags, flat cartons and film rolls nested.

Yes — mixed-SKU 40HQ loading is our standard service for distributors and 3PLs. Combine bags, boxes, mailers and films in one shipment with loading plans engineered to 70+ CBM, photo-documented layer by layer at loading.

We provide FDA / EU 10/2011 migration reports for food-contact laminates, FSC chain-of-custody certificates for paper products, ISTA-style drop and burst test reports for boxes, plus BSCI / SEDEX social audit certificates and ISO 9001. Full document packs support retail-chain and procurement audits.

Yes — we hold FSC Chain-of-Custody certification covering our converting operations in our own name, hold FSC credit accounts with our paper mills, and issue FSC transaction certificates per shipment linking your order to certified pulp. You can verify any transaction certificate number directly in the FSC database.

Yes. We produce under your brand with custom dielines, private-label prints, branded packing and pallet wrapping from 5,000 pcs. Neutral packaging is also available for traders. Dieline engineering support and pack-out testing are included in the program.

Every batch passes dimensional, burst, edge-crush and seal checks in our lab; films are gauge-tested per roll; print is color-checked against retained drawdowns. Pre-shipment we send you production photos, a loading video, and third-party inspection (SGS/BV/TÜV) can be arranged at your cost if required.

Standard terms: 30% TT deposit, 70% against B/L copy. Irrevocable LC at sight is accepted for orders above USD 20,000. We also support Alibaba Trade Assurance orders.

We currently ship to 45+ countries with the largest volumes to the United States, Germany, Japan, Brazil and Australia, and we are familiar with each market's import documentation, labeling and test requirements (FDA for the US, EU 10/2011 for Europe, food sanitation conventions for Japan).

It depends on three variables: product type, material grade and order volume. As a factory-direct reference: poly mailers and kraft bags sit at the entry tier per piece; printed mailer boxes and stand-up pouches cost more due to plate and laminate structure; rigid boxes bundle at the best per-piece cost in full containers. Ordering a full 40 ft HQ container typically cuts unit price and freight per unit by about 25-35% versus mixed LCL shipments — for flat-packed packaging, container utilization matters more than almost any other cost lever. Send us your product list, target quantities and destination port — we reply with an FOB quote within 24 hours.

For budget-driven buyers, start with stock-size plain kraft mailers and bags (no plate costs), add 1-2 color prints on your highest-volume items first, and reserve full-color rigid boxes for premium tiers. Mixed-SKU container loading lets you test 5-8 packaging lines with one freight cost. Plan flat-pack efficiency — nested bags and flat cartons load 70+ CBM per 40HQ versus under 50 for loose packing.

Three hidden drivers: material honesty (a genuine 60 micron co-ex film costs more than 40 micron regrind that punctures in sorting hubs — always ask for gsm/micron specs in writing), structural engineering (a proper dieline with pack-out testing protects your product; a traced copy of your old box may not), and compliance (FDA / EU 10/11 migration reports and FSC chain-of-custody cost real money but protect your retail program from audit failures). Comparing quotes on photos alone often backfires in this category.

Yes — food-contact laminates are built from FDA / EU 10/2011 compliant films, adhesives and inks, with migration testing per batch through accredited labs. Every laminate structure has a locked bill of materials and a declaration of compliance compiled per structure. packritepack.com/products/flexible-bags/

Yes — food-contact items carry FDA / EU 10/2011 compliance with per-batch migration reports; corrugate passes ISTA-style drop, burst and edge-crush tests; paper products offer FSC chain-of-custody certification; mailer films are heavy-metal free per REACH. We regularly supply importers who retail under US and EU requirements, and the standard document pack covers material, load and safety reports for each shipment.
