Cold-chain gel ice packs keep seafood, meat, produce and prepared food cold between the packing line and the buyer. Frozen solid before dispatch, they are laid into export cartons, insulated boxes and retail cold packs, then re-frozen between runs. Bofeng New Materials supplies standard and custom pack sizes with film options including food-contact grades.
How many packs, and at what gel weight, depends on box volume, insulation, loading temperature and the transit window rather than a fixed formula. Send us those four inputs and we will recommend a starting specification for trial shipments; packs can be printed and packed to your format.
FAQ
- Are the packs safe next to food? They use non-toxic, odour-free food-contact grade film and gel; documentation is provided offline for your market’s compliance review.
- How long do they keep a shipment cold? Hold time depends on gel weight, box volume, insulation and the ambient route; share box size, loading temperature and transit window for a starting recommendation.
- Can the packs be reused? Yes — they are designed to be re-frozen between runs; usable cycle life varies with handling and route.
- Can sizes, film and branding be customised? Yes. Gel weight, pack dimensions, film type and printed branding are made to order for the carton or insulated box.
- Can we run a cold-chain trial first? Yes. Send product type, box size and transit window and samples are arranged, so you can instrument a trial shipment before committing a specification.
