BOPP: Biaxially Oriented Polypropylene is understood to be a plastic polypropylene (PP) film that is biaxially stretched (i.e., in the longitudinal and transverse direction).
COEX: Coex is the abbreviation for co-extrusion and means that several extruders are used to produce the film. For example, one side of the film can be produced in white and the other in black (as with coex shipping bags) or any other color combination. PA/PE vacuum bags are also produced with one side of the film made of PA and the other of PE.
CPP: Cast Polypropylene is an unstretched polypropylene. Like polypropylene (PP), CPP is a semi-crystalline thermoplastic and belongs to the group of polyolefins. Compared to conventional PE films, CPP is characterized by exceptionally high transparency, rigidity, and abrasion resistance. These properties make CPP, along with OPP (Oriented Polypropylene), the most widely used polymer in the packaging industry. Main areas of application are the packaging of food, textiles, or medical items, and as a lamination layer in multilayer films.
ESD: An ESD film is a material specially developed to protect electronic components from static discharges.
EVOH: Ethylene-vinyl alcohol copolymer – EVOH for short – is a copolymer that is formally composed of the two monomers ethene and vinyl alcohol (ethenol). In processing, EVOH is either extruded or applied as a thin film layer and is generally used as a barrier layer.
HDPE: (High-Density Polyethylene) is the abbreviation for hard polyethylene. This type of polyethylene owes its high density to a special manufacturing process and is harder than other types of polyethylene due to this higher density.
LDPE: Low-density polyethylene, LDPE, is a thermoplastic polymer made from the monomer ethylene. It is a highly branched plastic, which gives it a low density as well as lower hardness, rigidity, and melting temperature.
MDPE: stands for Medium Density Polyethylene. It closes the gap between LDPE and HDPE. Both the properties of LDPE and HDPE are combined into one product.
MOPP: Monoaxially Oriented Polypropylene film (MOPP) is a type of uniaxially stretched polypropylene.
MPET: Metallized Polyethylene Terephthalate
OPP: OPP is the abbreviation for Oriented Polypropylene. This is the plastic material polypropylene, which has been pre-stretched as a film product. The film is stretched either monoaxially in one direction, or biaxially in the longitudinal and transverse direction.
PBAT: Polybutylene adipate terephthalate, a biodegradable and compostable copolymer from the polyester group.
PE: Polyethylene is a semi-crystalline and non-polar thermoplastic. PE, as polyethylene is abbreviated, is mainly used for packaging and films. Polyethylene is produced by the polymerization of ethene.
PET: Polyethylene terephthalate (abbreviation PET) is a thermoplastic plastic produced by polycondensation from the polyester family. PET has a wide range of applications and is used, among other things, for the production of plastic bottles (PET bottles), films, and textile fibers.
PLA: Polylactides (short PLA) are synthetic polymers that belong to the polyesters. Plastic is made from them, which is obtained from renewable sources (such as corn starch). This makes PLA a biocompatible raw material.
PP: Polypropylene has great similarities with PE-LD; it is characterized by high stability and is resistant to many chemicals. It is also physiologically harmless and not harmful to the environment in the recycling process. However, polypropylene is harder and more heat-resistant than PE-LD.
PPE: Polyphenylene ether (abbreviation PPE, also poly or polyether, formerly called polyphenylene oxide, PPO) is a high-temperature-resistant, thermoplastic plastic.
PVC: Polyvinyl chloride is, besides PE, PS, and PP, the best-known plastic, especially in the packaging sector, where the first adhesive tapes were made of PVC. Polyvinyl chloride is produced by the polymerization of chloroethene (also vinyl chloride).
VCI: VCI stands for Volatile Corrosion Inhibitors. VCI are incorporated into carrier materials such as film and paper. When parts are packaged in VCI film or VCI paper, the active ingredients evaporate and form a protective atmosphere against corrosion inside the packaging.
VMPET: VMPET is the abbreviation for Vacuum Metalized Polyethylene Terephthalate and is often also referred to as METPET or MET/PET. PET-VMPET-PE packaging film consists of three different layers: an outer PET layer, a middle VMPET layer, and an inner layer of low-density polyethylene.
RECYCLED MATERIAL (or RECYCLATE): Recycled material is the product of a recycling process and accordingly stands for substances and objects that consist wholly or partly of recycled materials. So, waste is recycled. Recycling is possible for almost all materials, e.g., for plastics, cardboard, paper, wood, or glass. However, the term "recycled material" is mostly used in connection with plastics.
ADHESIVE SEAL BAG: An adhesive seal bag is a film bag or flat bag, usually made of PE or PP, with a self-adhesive flap at the opening. The self-adhesive flap serves as the closure of the bag. The adhesive closure is provided with a film or paper cover, which is peeled off.
U-CLIP & CLIP BANDS: U-CLIP & CLIP BANDS – the optimal closure for block-bottom bags and various other bag and pouch packaging.
