Flexible packaging with printing — ready-made bags, sachets, stick packs, doypacks made from multi-layer laminated films with rotogravure or flexographic printing up to 10 colors. Doypack (stand-up pouch): a stable bag with a bottom gusset and zipper — replaces cans and bottles, reduces packaging weight by 80%. Sachet: a portioned flat bag 5–100 ml for sauces, creams, shampoos. Stick pack: a narrow vertical bag for powders, sugar, coffee. Materials: PET/PE, PET/AL/PE, OPA/PE, PET/EVOH/PE — selected according to the product (barrier properties, heat resistance, transparency). Additional options: zipper, spout, degassing valve (for coffee), tear notch, euro hole. Minimum order quantity from 5000 pcs. FFS (Form-Fill-Seal): vertical and horizontal packaging machines form a bag from roll film, fill it with product and seal it — an automatic process 60–200 packs/min. Film for FFS: heat-sealable, with predictable shrinkage. Degassing valve (one-way valve): for coffee — releases CO₂ from freshly roasted beans without letting oxygen in. Documentation: print layout, material specification, seam strength test (seal strength ≥15 N/15 mm).
