A buyer's guide to water soluble packaging.
Short answers to the questions buyers ask before they order: which grade, which format, and what to send us for an exact quote.
Guide 1
Hot or cold water soluble: which do you need?
Choose the grade by when the pack should open.
Cold water soluble film dissolves at room temperature. Choose it when the pack goes straight into a pond, spray tank, cistern, mixer or wash water: sachets, aquaculture feed and probiotics, agrochemical and dye packs.
Hot water soluble film softens in cold water and dissolves above 65°C. Choose it when the bag must stay closed until it meets hot water: hospital laundry bags and garment bags.
Guide 2
Pouches or film rolls: which suits your line?
Ready-made pouches suit manual and semi-automatic filling. We supply empty pouches cut to your size; your team fills them and seals them on a heat sealing machine.
Film rolls suit high-speed automatic lines. Your form-fill-seal machine forms the sachet from our roll, fills it and seals it in one run. Tell us the roll width your machine takes, and whether you need a single film roll or a tube roll.
