Product families to evaluate
Material selection follows end-use risk. These families are candidate starting points, not unverified suitability claims.
Nylon zippers
Nylon zippers are a practical starting point for projects that need a flexible opening, relatively light construction or curved-path adaptability. No. 5 open-end configurations are often discussed for jackets, while larger gauges, closed-end and two-way configurations can extend to bags and equipment. Final suitability must be verified in the finished product.

Resin zippers
Resin zippers suit products where the teeth are intended to become a visible design element or where strong color expression and a defined structural line are desired. Smaller open-end directions can support childrenswear and lightweight jackets; larger open- or closed-end directions can be evaluated for bags, heavier jackets and equipment.

Metal zippers
Metal zippers suit products that emphasize authentic material character, vintage styling or refined hardware details. No. 3 trouser zippers support compact constructions, while larger open-end directions such as No. 8 create a stronger visual and structural presence. Finish durability must be verified for the actual environment.
View detailsFrequently asked questions
Does every bag need two sliders?
No. Two sliders improve directional access but add construction and orientation decisions.
Is a larger zipper automatically stronger?
No. Chain, slider, sewing and load path all affect the finished product.
How should a curved opening be validated?
Install it on the production pattern and test empty, loaded and repeated operation states.
