Wholesale Zips for Clothing, Bags and Footwear

Wholesale zips for garment production

A zip is a small detail, yet it decides whether a garment is enjoyed for years or comes back as a complaint. That is why, when buying zips wholesale, it is not only price and colour that matter but also the tooth type, size, slider style and how the zip is sewn in. Polkom is a Bulgarian company based in Sofia with more than three decades of experience in garment accessories. We supply zippers to fashion brands, clothing manufacturers, ateliers and traders across Europe – from single samples for a new collection to full production runs.

Every zip consists of two textile tapes, a row of teeth (the chain) along their edges, a slider with a puller, and stops at the ends. The combination of these elements determines strength, flexibility and appearance. That is why our range is built around four main zip groups, each with a clear purpose.

Types of zips in our range

Metal zips

Metal zips have teeth made of brass, aluminium or nickel-plated alloy. They are the classic choice for jeans, jackets, leather goods and bags – strong, with a distinctive sound and look. Finishes include nickel, gold, antique brass, bronze and black nickel.

Nylon coil zips

Nylon coil zips feature a continuous nylon spiral stitched to the tape. Light and flexible, they follow the curves of the pattern and are the most versatile choice for dresses, trousers, sweatshirts, pouches and home textiles.

Moulded plastic zips

Moulded plastic zips have individual plastic teeth injection-moulded directly onto the tape, most often from polyacetal (POM). They do not rust and withstand moisture and cold, which is why they are preferred for sports jackets, outerwear, backpacks and workwear.

Invisible zips

Invisible (concealed) zips are coil zips with a reversed chain: once sewn in, only the small slider puller shows on the outside. They are used in dresses, skirts, formalwear and cushion covers.

Sizes, lengths and constructions

Zip size is indicated by a number that roughly corresponds to the width of the closed chain in millimetres. The most common sizes in apparel are:

• No. 3 – fine garments, dresses, pockets, light skirts;
• No. 5 – the all-round size for trousers, jeans, jackets and bags;
• No. 8 and No. 10 – heavy jackets, coats, backpacks, luggage and outdoor gear.

By the way they open, zips are closed-end (joined at the bottom – for trousers, pockets, skirts), open-end/separating (for jackets and sweatshirts that open fully) and two-way (with two sliders – for long jackets, parkas and sleeping bags). As well as ready-made zips in fixed lengths, many models can also be ordered in custom lengths.

Colours, finishes and sliders

Tapes are dyed in a wide palette and can be matched to a fabric swatch or a Pantone reference. With metal zips you also choose the tooth finish, and with moulded zips whether the teeth match the tape or contrast with it. Sliders matter too: auto-lock (self-locking) sliders for trousers, non-locking sliders for cushions and bags, double-sided sliders for reversible garments, plus decorative pullers.

Custom zips with your logo

For brands that want a recognisable detail, we offer sliders and pullers with a logo, custom shapes and colour combinations tailored to the collection. The zip can become part of the product's visual identity – especially on jackets, bags and sportswear. Our services also include sample making, logo engraving, attaching zips and accessories, and advice on choosing the right type.
