Import 3#Nylon Zipper Long Chain — Buy in Bulk from Supplier in China

The 3#Nylon Zipper Long Chain from Shenzhen Do-Well Industry And Trade ) Co., Ltd is a continuous coil zipper supplied in bulk roll form rather than pre-cut lengths. Each coil contains 400 yards of chain with a declared weight of 3.5 kg per coil, indicating a linear density that buyers can use to estimate yield for their cutting operations. The product is offered in standard black with colour customisation available on request. Long chain format means sliders are purchased and applied separately by the buyer or their subcontractor, giving flexibility in matching slider type to end-use requirements.

Nylon coil zippers at gauge 3 use a continuous monofilament coil sewn onto polyester or polyester-cotton tape, with typical coil diameter of 2.8-3.2 mm and tape width of 25 mm for standard applications. The supplier specifies industrial-grade nylon without declaring denier, tensile grade, or whether the coil is mono-filament or multi-filament construction. Standard coil materials are nylon 6 or nylon 66, with nylon 66 offering higher melting point and better abrasion resistance for demanding applications. The 3.5 kg per coil weight implies approximately 8.75 grams per yard, which is consistent with standard gauge 3 coil construction with polyester tape backing.

This product serves manufacturers of fashion garments, outdoor equipment, and home textiles who operate in-house zipper cutting and slider attachment. The 400-yard coil suits medium-batch production, while the 4,000-yard bulk bag targets high-volume users with automated cutting equipment. Buyers should confirm coil memory characteristics, as nylon coil with poor heat setting will curl off the roll and jam automatic machinery. Standard applications include sleeping bags, tents, sportswear, and upholstery where the tape can be sewn directly into seam allowances. The supplier mentions flexible MOQ without stating figures; direct confirmation is needed for planning purposes.

Shenzhen Do-Well Industry And Trade ) Co., Ltd lists this nylon zipper alongside its metal zipper offering, suggesting a diversified fastener trading business rather than single-product specialisation. The company holds imported supplier tier and harbor trust tier classifications, with zero recorded response activity. No factory size, production line count, or R&D capability is disclosed. The supplier name implies Shenzhen as operational base, but no specific district, industrial park, or warehouse address appears in the profile data provided.

The listing does not indicate whether this supplier manufactures nylon coil in-house or sources from a dedicated zipper mill. No named certifications, patent holdings, or major client references appear. For a long chain zipper buyer, this ambiguity matters because coil quality consistency, dye lot matching, and coil memory stability depend heavily on extrusion and heat-setting equipment that trading companies may not control. Buyers should request supplier assessment questionnaire, factory audit possibility, and evidence of quality management system implementation before establishing volume commitments.
