Both metallised PET and PP have replaced foil laminates for products such as snack foods, coffee and candy, which do not require the superior barrier of aluminium foil. Metallised nylon and polyethylene are used in the meat export market. The controlled permeation extends shelf life.
BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation. [1] When metallized, it has [3] gas and moisture barrier ...
Production of 1 tonne (0.98 long tons; 1.1 short tons) of plastic cups emits 135 pounds (61 kg) of green house gases. The choice between paper cups and plastic cups has to do with the life of the item after use. A paper cup may biodegrade faster than a expanded polystyrene (EPS) foam cup or a plastic cup. In general cardboard or paper takes one ...
A bag-in-box or BiB is a container for the storage and transportation of liquids. [1] It consists of a strong bladder (or plastic bag), usually made of several layers of metallised film or other plastics, seated inside a corrugated fiberboard box. [1] The BiB is used because of its easy transportation and ability to dispense liquids.
In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym PET is generally used in relation to packaging. [ citation needed ] Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).
[1] [2] [3] FIBCs are most often made of thick woven strands of oriented polypropylene, [4] either coated or uncoated, and normally measure around 45–48 inches (114–122 cm) in diameter and varies in height from 100 to 200 cm (39 to 79 inches). Its capacity is normally around 1,000 kg or 2,200 lb, but the larger units can store even more.
Polypropylene film capacitors (PP) 0.05 to 0.1% Polyester film capacitors (PET) 0.2 to 0.5% Polyphenylene sulfide film capacitors (PPS) 0.05 to 0.1% Polyethylene naphthalate film capacitors (PEN) 1.0 to 1.2% Tantalum electrolytic capacitors with solid electrolyte: 2 to 3%, [57] 10% [58] Aluminium electrolytic capacitor with non solid ...
The introduction of plastics in plastic film capacitors was approximately in the following historic order: polystyrene (PS) in 1949, polyethylene terephthalate (PET/"polyester") and cellulose acetate (CA) in 1951, polycarbonate (PC/Lexan) in 1953, polytetrafluoroethylene (PTFE/Teflon) in 1954, polyparylene in 1954, polypropylene (PP) in 1954 ...
