Cardboard Envelope
This cardboard envelope is manufactured from paper with a grammage of 250 - 350 gsm and a thickness range of 0.32 cm to 0.45 cm, providing rigidity for protecting documents and small items during transit. The design includes a strong self-adhesive seal to prevent tampering, complemented by easy-tear release paper for quick opening. The envelope is available in grey, white, or custom colours, with FSC-certified recyclable materials as a standard option.
Chipboard envelopes of this type typically conform to ISO 216 or DIN 6781 standards for dimensions, with common sizes ranging from C4 to C6. The 250 - 350 gsm range is standard for courier envelopes, balancing durability with flexibility for insertion. Waterproof Kraft variants often include a polyethylene coating, though the listing does not confirm this for all models.
These envelopes are used by e-commerce businesses for shipping lightweight goods, corporate clients for document distribution, and marketing teams for mailing brochures. The supplier’s production capacity is 10,000 pieces per day, with a lead time of 7 days for orders of 10,000 units. Buyers must confirm MOQ, Incoterms, and port details (Shenzhen is specified) directly with the supplier.

Sourcing Cardboard Envelope from Shenzhen Pack Technology Co., Ltd. - China Import Guide
Before ordering, confirm the grammage and thickness to ensure it aligns with your item’s weight and fragility. Request samples to test the self-adhesive seal’s strength and the easy-tear feature under your handling conditions. Verify if the Kraft variant includes waterproofing if moisture resistance is required for your shipments.
Logistics details to clarify include Incoterms (FOB Shenzhen is likely), packaging for bulk orders (cartons are standard), and whether the supplier can consolidate multiple SKUs into a single shipment. Lead times for custom sizes or prints may exceed the 7-day standard, so confirm production schedules for non-standard requests.
Quality checks should include measuring the grammage with a precision scale and testing the burst strength using a Mullen tester. Inspect the adhesive seal for uniform application and the easy-tear strip for clean separation. Request a pre-shipment inspection report to ensure the envelopes meet your specifications for dimensions, print quality, and material integrity.
