Tobacco packaging material testing

Introduction

Common plastic packaging includes plastic packaging boxes, calcium plastic corrugated boxes, plastic barrels, plastic bottles, plastic hoses, trays, boxes, plastic film bags, composite plastic film bags, plastic woven bags, and foam plastic sewing packaging, etc. Suitable for packaging of food, medicine, textiles, hardware and electrical products, various equipment, clothing, daily necessities, etc.

Testing products

[Related packaging materials]

      Polyethylene (PE, LDPE, HDPE, LLDPE, EPE), polypropylene (PP), polystyrene (PS)

      Polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyvinylidene chloride (PVDC), polyamide (PA)

      Polyvinyl alcohol (PVA), ethylene-vinyl acetate copolymer (EVA), polycarbonate (PC), polyurethane (PVP)

      Phenolic plastics (PE), urea-formaldehyde plastics (UF), melamine plastics (ME)

[Specific packaging materials]

      Plastic film: mainly low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP) and polyvinyl chloride (PVC) materials.

      Plastic bottles, barrels, cans and hose containers: The materials used are mainly high- and low-density polyethylene and polypropylene, but also resins such as polyvinyl chloride, polyamide, polystyrene, polyester, and polycarbonate.

      Cups, boxes, trays, boxes and other containers: foamed or non-foamed sheets of high and low density polyethylene, polypropylene and polystyrene are used for packaging food.

      Shockproof and cushioning packaging materials: foam plastics made of polystyrene, low-density polyethylene, polyurethane and polyvinyl chloride.

      Sealing materials: sealants and bottle cap linings, gaskets, etc., used as sealing materials for barrels, bottles, and cans.

      Strip material: packing tape, tear film, adhesive tape, rope, etc. Use polypropylene, high-density polyethylene or polyvinyl chloride tape blanks, oriented uniaxially.

      Composite flexible packaging materials: flexible packaging, aluminized film, iron core wire, aluminum foil composite film, vacuum aluminized paper, composite film, composite paper, BOPP, etc.
