What We Make — Seal Liners for Every Cap and Jar Closure
Taizhou Rimzer manufactures the sealing component that sits inside a cap: induction seal liners, foam and PS gaskets, hot melt liners, vented liners and closures. Every product in the range solves the same basic problem — keeping what is inside the bottle inside the bottle — but the right choice depends on your contents, your closure material and your filling line.
Induction seal liners
A foil-based liner that bonds to the bottle mouth when the filled cap passes under an induction sealer, creating a hermetic, tamper-evident membrane. Supplied as two-piece (foil disc plus backing) or one-piece (single laminate) construction. The usual choice for liquids, oils and pharmaceuticals that must be leak-proof.
Foam & PS gaskets
Compression liners that seal under cap torque alone — no equipment required. PE foam is soft and forgiving, ideal for jars and caps with slight surface irregularities; PS gaskets are firmer and cost-effective for dry goods, spices and cosmetics.
Hot melt & Lift-N-Peel
Hot melt liners pour and set into the cap, giving a reliable seal on glass and PET with a clean peel on opening. Lift-N-Peel liners add a tab so the consumer can reseal or peel cleanly — popular for sauces, dairy and nutraceuticals.
Vented liners, valves & caps
For products that generate gas or must breathe, vented liners, vented valves and vented caps allow pressure to equalise while blocking liquid and contamination — standard in agrochemicals, bleach and enzyme detergents.
How to Choose the Right Liner
| If your product is… | Start with | Why |
|---|---|---|
| Liquid, oil, syrup, juice | Two-piece induction seal liner | Foil membrane gives a leak-proof, tamper-evident seal with a wide tolerance for bottle-mouth finish |
| Cream, cosmetic jar, wide-mouth | PE foam gasket | Soft foam compresses into the jar rim and seals without induction equipment |
| Dry powder, spice, tablet | PS gasket or one-piece foil | Firmer disc stays seated; foil version adds moisture barrier |
| Agrochemical, bleach, peroxide | Vented liner, valve or cap | Equalises internal pressure while keeping liquid in and contamination out |
| Sauce, dairy, nutraceutical | Lift-N-Peel liner | Tab allows clean peel and reseal, better consumer experience |
| Injectable, vaccine | Aluminium-plastic ampoule cap | Hermetic crimp seal with drug-contact-safe liner |
