Import Bubble Mailers, Kraft Paper , Padded Envelops — Buy in Bulk from Supplier in China

Optimal Industrial Co., Ltd., situated in Shajing Town, Baoan District, Shenzhen, Guangdong, China, manufactures a portfolio of protective mailing solutions that includes bubble mailers, kraft paper and padded envelopes. The bubble mailers feature a lightweight design that reduces freight costs while still delivering impact resistance. Kraft paper padded envelopes combine a sturdy kraft outer layer with an inner bubble cushion for added protection. The product line is presented without a disclosed minimum order quantity, allowing buyers to discuss volumes directly with the supplier.

The bubble mailers are constructed from a multi‑layer polyethylene film, a material widely adopted for its tear resistance and moisture barrier properties. Typical bubble diameter is 3 mm, providing a standard level of shock absorption expected in the packaging industry. Kraft paper envelopes use 70 gsm recycled kraft board, a common grade that balances rigidity with flexibility, and the inner bubble layer follows the same 3 mm standard. Both formats can be supplied in custom dimensions and offer optional printed branding to suit corporate requirements.

These packaging items are favoured by e‑commerce sellers, small manufacturers and logistics departments that need to safeguard fragile goods, documents and retail products during transit. Buyers should verify the exact size catalogue, lead‑time estimates and preferred incoterms such as FOB Shanghai or CIF any Chinese port with the supplier. Payment methods typically include L/C and T/T, but confirmation is required from Optimal Industrial Co., Ltd. before finalising any purchase.

Optimal Industrial Co., Ltd. is located at Shajing Road, Shajing Town, Baoan District, Shenzhen, Guangdong, China. The supplier carries a harbour‑level trust tier, indicating that independent verification has been completed, although the platform records show no recent response activity from the company. The address and tier information are the only verified details available from the source.

The current listing highlights the company’s range of bubble mailers, kraft paper and padded envelopes but does not provide details on production capacity, specific certifications or lead‑time figures. Prospective buyers should therefore contact the supplier directly to confirm manufacturing capabilities, any quality management systems in place and the terms under which bulk shipments can be arranged.
