Side seal bags are superior in strength to side weld bags as the seals are manufactured using a heat-sealing bar giving seals around 5mm in width compared with side welds that are produced using a hot knife. Accordingly, side seal bags are used to pack bulkier and heavier products in both the food and non-food industries where watertight seals are essential. We can incorporate a bottom gusset to transform the side seal bag to a stand-up pouch bag.

Accordingly we can manufacture bags from 25 – 1000mm in width and with lengths up to 400mm.
