About Beijing Lianbin Plastics & Printing Co., Ltd - Zipper Bags Supplier in China

Beijing Lianbin Plastics & Printing Co., Ltd is located in Beijing, China and currently lists five active products in its catalogue. The catalogue contains a flat bag, a zipper bag, a handle bag, a draw‑string bag and an envelope, all of which fall under the broader plastic bag segment. Each item is presented as a separate SKU and the supplier classifies its offering under the “Zipper Bags” top category despite the varied closure styles. The product list reflects typical packaging formats used for retail, promotional and bulk distribution purposes. The supplier is marked as an imported tier with a “harbor” trust tier, indicating that it operates through standard import channels without additional verification layers.

The five listed items are all manufactured from flexible plastic films and are intended for secondary packaging or direct consumer use. The flat bag and envelope are simple open‑top formats, while the zipper, handle and draw‑string bags incorporate re‑closable features that add convenience for end‑users. No specific HS codes are supplied in the catalogue, but the items belong to the plastic packaging family commonly classified under chapter 39 of the Harmonized System. The supplier’s catalogue does not disclose material thickness, dimensions or bulk packaging quantities, leaving those details to be confirmed during the sourcing process.

Product Range and Specialties of Beijing Lianbin Plastics & Printing Co., Ltd

The catalogue’s five products cover the main closure types used in flexible plastic packaging. Flat bags are typically produced from low‑density polyethylene (LDPE) or linear low‑density polyethylene (LLDPE) with thicknesses ranging from 30 to 80 µm. Zipper bags usually incorporate a molded‑in‑place (MIP) or extruded zipper made of polypropylene (PP) and are offered in thicknesses of 40‑100 µm. Handle bags add reinforced strips or woven handles, often using a higher‑grade HDPE film of 50‑120 µm to support load. Draw‑string bags employ a sewn or heat‑sealed draw‑string, with film grades similar to flat bags but reinforced at the top edge. Envelopes are thin, single‑wall bags, frequently produced in 20‑40 µm thickness for document or lightweight item transport. Industry practice groups these items by material (LDPE, HDPE, PP), thickness, and intended load, and buyers normally specify dimensions (e.g., 30 × 40 cm, 45 × 60 cm) and closure style when requesting a quote.

Typical industry specifications also include moisture barrier ratings (water vapor transmission rate), tensile strength (often 10‑30 MPa for HDPE films) and printable surface finish (gloss or matte) for branding. Bulk packaging is usually in cartons of 500‑2 000 bags or bulk rolls for secondary conversion, and a standard 20‑ft container can accommodate roughly 15 000‑20 000 standard‑size plastic bags depending on packing density.

Trade and Export Information - Beijing Lianbin Plastics & Printing Co., Ltd

China is one of the world’s largest exporters of flexible plastic packaging, and items such as flat, zipper, handle and draw‑string bags are regularly shipped to North America, the European Union, the Middle East and Southeast Asian markets. The products fall under HS chapter 39, specifically HS code 3923 for “plastic articles for the conveyance or packaging of goods.” Importers commonly require compliance with REACH (EU) and, where food contact is intended, FDA food‑contact regulations or EU Regulation No 1935/2004. Standard certifications that Chinese exporters hold include ISO 9001 for quality management and, for certain grades, ISO 14001 environmental certification. Typical export logistics use FOB Shanghai or Ningbo ports, with buyers often arranging CIF or DDP terms. A 20‑ft container can hold up to 20 000 standard‑size bags, while a 40‑ft container can double that volume. Documentation normally includes a commercial invoice, packing list, certificate of origin, material safety data sheet (MSDS) and any requested test reports (e.g., ASTM D6400 for biodegradability).

Sourcing from Beijing Lianbin Plastics & Printing Co., Ltd - Buyer Guidance

When evaluating Beijing Lianbin’s offerings, buyers should request a material data sheet that details film type (LDPE, HDPE, PP), thickness, melt‑flow index and any food‑grade certification. Samples of each bag style are advisable to verify seal strength, zipper durability and handle load capacity; industry tests such as ASTM D1004 (tensile strength) and ISO 9001 audit reports are standard verification tools. Buyers should also confirm that the supplier can provide REACH compliance statements or FDA food‑contact approval if the end use requires it. Typical minimum order quantities for custom‑size plastic bags range from 5 000 to 10 000 pieces per style, with lead times of 20‑35 days after artwork and specifications are finalized. Packaging is usually in export‑grade cartons, and buyers should specify container loading preferences (20‑ft or 40‑ft) and preferred Incoterms before finalizing the order.
