The production of eight-sided sealed coffee bags first requires the selection of appropriate materials. Common materials include OPP, PE, CPP, PET, nylon, pure aluminum, and aluminum-coated materials, etc. The choice of these materials will affect the barrier performance, heat sealing performance, moisture-proof performance, and transparency of the packaging bag. For example, pure aluminum or aluminum-coated materials can provide good oxygen and light barrier properties, while nylon materials have high strength and toughness.
Eight-sided sealed coffee bags are usually printed to increase the product's attractiveness and brand recognition. The printing process includes electro-engraving copper plate high-speed printing, which can achieve high-definition pattern and text printing.
