Finished Roll Material for Seal Liners

Finished Roll Material for Seal Liners — Ready for In-House Die-Cutting

Finished roll material is a multi-layer laminate supplied in continuous rolls rather than as pre-cut discs — designed for customers who die-cut their own liners in-house. Instead of buying finished gaskets at a fixed diameter, you receive the full laminate — hot-melt sealing layer, aluminium foil, PET and PE foam, plus the insulation layer — pre-combined and wound to your width, so that your existing die-cutting press produces liners in any diameter you need, on the day you need them.

The advantage is flexibility and material economy: one roll covers every cap size in your range, cuts waste on short runs and changeovers, and removes the lead time and freight cost of shipping bulky pre-cut discs. Rimzer controls the lamination in-house, which means adhesive viscosity, foil adhesion and layer thickness can all be tuned to your cap material — PE, PP or aluminium — and to the sealing strength your filling process needs. Standard rolls run 50mm to 600mm wide and 30m to 600m long, with common specifications held in stock in our 2,000 m² warehouse for 2–4 day delivery.

Specifications

Applications

Supplied to cap manufacturers, closure converters and in-house lining operations in South America, Southeast Asia, Europe and the Middle East. Typical uses include:

• Cap manufacturers with in-house lining — die-cut liners directly into PP, PE or aluminium closures on your own press.
• Converters serving multiple brands — one roll covers every diameter in your catalogue, so short runs stay economical.
• Induction seal liner production — two-piece and one-piece induction liners from a single laminate.
• Hot-melt liner production — adhesive layer tuned to your sealing temperature and dwell time.
• Beverage and dairy closures — foil-plus-foam laminates for aseptic and ESL filling.

Key Advantages

• One roll, every diameter — no need to forecast each cap size separately; cut what you need, when you need it.
• Lower material waste — continuous rolls eliminate the trim loss and offcut scrap typical of ordering many fixed diameters.
• No disc freight cost — rolls ship far denser than pre-cut gaskets, cutting freight and warehouse space significantly.
• Adhesion tuned to your cap — adhesive viscosity is adjusted for PE, PP or aluminium closures so the liner bonds reliably after die-cutting.
• Consistent layer thickness — every roll is tested for thickness uniformity, so your press settings stay stable across the run.
• Stock availability — common specifications held in our 2,000 m² warehouse, shipping in 2–4 days.

Why Choose Taizhou Rimzer

Taizhou Rimzer Rubber & Plastic Co., Ltd has over 20 years of experience in seal liner manufacturing, with a 23,000 m² facility and 85 skilled staff serving 100+ customers worldwide. Because we laminate the material ourselves rather than buying it in, we can adjust layer structure, adhesive viscosity and roll dimensions to your process — and we make the finished liners too, so we understand exactly how the roll will behave on your die-cutting press. Every roll is tested for thickness uniformity and peel strength before shipment.

Frequently Asked Questions

What exactly is "finished roll material" — is it the same as liner stock?

It is the complete laminate, ready to die-cut: hot-melt adhesive, aluminium foil, PET, PE foam and insulation layer already combined in the correct order. You do not need to laminate anything further — you only need to die-cut the discs.

What width and length should I order?

Match the roll width to your press web width and the largest diameter you cut, so you get the most discs per metre. Length depends on your consumption: many customers order 100–300m per specification for a first run. Send your cap diameter range and monthly volume and we will recommend a starting order.

Will it run on my die-cutting press?

Yes — the laminate is formulated for standard rotary and flatbed presses. Tell us your press type, cutting speed and die specification, and we will confirm the layer structure and release characteristics.

Can the adhesive be tuned to my cap material?

Yes, that is the main reason customers buy rolls rather than finished discs from us. Adhesive viscosity and foil adhesion are adjusted for PE, PP or aluminium closures so that the liner bonds firmly after die-cutting and does not shift in the cap.

What is the shelf life and how should I store it?

12 months from production in unopened packaging, stored at 15–30°C away from direct sunlight and humidity. Hot-melt adhesive can lose tack if stored hot; keep rolls in the original moisture-barrier bag until use.

Is the material food-contact compliant?

Yes — the laminate complies with FDA and EU 10/2011 food-contact requirements, and SGS test reports are available for your regulatory file.

What is the MOQ?

500 kg per specification. Because rolls are dense, 500 kg is a substantial length — often 300–600m depending on width and thickness.

Can I get samples before ordering?

Yes, we supply a sample length of the standard structure free of charge so you can trial it on your press. Sample length and courier cost are negotiable.
