A mouthfuled pouch is formed by attaching a capped low pressure polyethylene (HDPE) to the bag (typically a stand-up pouch). In addition to the advantages of easy opening and sealing for bottles and barrels, the bag with mouth has the advantages of less packaging material consumption, high printing and decoration Read more…

PVC: Polyvinyl chloride film, density 1.39g/cm3, transparent, flame retardant, extinguished from fire, irritating hydrochloric acid. It is divided into three categories: hard, semi-rigid and soft, which are distinguished by the content of plasticizer in the material. At present, most of them are used for twisting PVC and shrinking PVC. Main Read more…

PE: unstretched polyethylene, density: 0.96 g/cm3. Not sinking in water, flammable, burning when the flame is blue, the upper part is yellow, and there is a paraffin smell. The flexible packaging industry commonly uses low density (LDPE), linear low density (LLDPE), high density (HDPE), and is divided into casting (CPE) Read more…

BOPP: Biaxially oriented polypropylene film with a density of 0.96/cm3, flammable, burning blue under the flame, yellow upper part, a small amount of black smoke, petroleum flavor. Main Performance: 1, colorless, high transparency 2. Excellent tensile strength, impact strength and stiffness 3, excellent cold resistance, heat resistance: -40 ~ 120 Read more…

Bubble Phenomenon The so-called bubble means that the two layers of film are not completely bonded, and the composite finished film and the substrate have a gap and a gas, and when the aluminized film is combined, a white point like a needle tip is generated. Essentially, the applied glue Read more…

The abnormality of the solventless composite process in flexible packaging is usually caused by objective factors such as paper, film, ink, adhesive, machine equipment, and subjective factors such as temperature, pressure, speed, amount of glue, and customer use. According to the actual application of the adhesive in the composite process, Read more…
