A PVA bag holds your bait in a neat measured dose, dissolves the moment it hits water, and leaves nothing behind. We make the film cold-water grade because fishing water is ambient — no wash cycle, no heat, just lake, river or sea.
A PVA fishing bag carries bait — boilies, pellets, groundbait, particles — in a pre-measured dose. You cast it out with the rig. The bag hits the water, the film dissolves, and the bait lands in exactly the spot you aimed at, in one tight pile instead of a scattered trail.
For an angler, that means a tighter feed pattern and a bag that doubles as a feeder. For a brand selling to anglers, it means a product people rebuy in bulk, and one where the film grade decides whether it works at all.
| Specification | What we supply |
|---|---|
| Formats | Flat bags, tubular mesh, stringer tube, flat sheet, rolls for filling on your own line |
| Film grade | Cold-water PVA, 20–30 °C — the grade that dissolves in ambient lake, river or sea water |
| Dissolving speed | Tuned at sampling: fast for a quick release, slower where the bag must survive the cast and the descent |
| Size | Made to your dimensions — width, length, tube diameter |
| Thickness | Set at sampling against your dissolving time and how rough the cast is |
| Unprinted, or printed with your logo and product name | |
| Packing | Bulk cartons, or retail-ready packs under your brand |
Water temperature in a lake or river is ambient — around 5 °C in winter and 22 °C in summer. There is no heat to help the film along. A warm-water or hot-water grade would still be sitting there as a bag an hour after the cast, which is the single most common complaint about badly sourced PVA bags.
Cold-water film is formulated to break down in that 20–30 °C band and below. The exact dissolving time is set by film thickness and formula, which is why we tune it during sampling rather than quoting a number up front.
Send your spec. We come back within one business day with a film recommendation, the sample plan and the timing. You test the samples on your own bait and in your own water. Only when the film performs do we move to bulk production, quality check and shipping.

The questions buyers ask most about this application.
Cold-water PVA film, rated for around 20–30 °C and below. Fishing water is ambient, so there is no wash cycle or heat to help the bag dissolve. The exact dissolving time is tuned by film thickness and formula at sampling.
It depends on the thickness and the formula we set for you, plus the water temperature on the day. We tune it to your requirement during sampling — faster where you want a quick release, slower where the bag has to survive the cast and sink first.
Yes. We supply flat bags, tubular mesh, stringer tube, flat sheet and rolls for customers who fill on their own line. Send the tube diameter and length you need.
Yes. Bags can be supplied unprinted or printed with your logo and product name, and packed in retail-ready packaging under your brand.
It depends on the bag size, the film grade and whether the pack is printed. Send your target quantity with your enquiry and we confirm the exact minimum, unit price and lead time in the written quote before you commit.
