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 ...
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.
Polyethylene terephthalate (PET, PETE) / Polyester This resin is commonly used for carbonated beverages, water bottles, and food packaging. PET provides very good alcohol and essential oil barrier properties, generally good chemical resistance (although acetones and ketones will attack PET), and a high degree of impact resistance and tensile ...
Voltage derating between upper rated temperature (85 °C for PP, PET and 105 °C for PEN, PPS), and upper category temperature The rated DC voltage V R is the maximum DC voltage, or peak value of pulse voltage, or the sum of an applied DC voltage and the peak value of a superimposed AC voltage, which may be applied continuously to a capacitor ...
The cups are great quality, she notes, so if you drink from the cups daily and consider each day of use worth a dollar, it’s well worth it. “I’m a dancer, so a water bottle is always with me ...
But it’s only within the last several years that researchers have discovered the extent to which microplastics (which range from 1 nanometer, 1/80,000 the width of a strand of hair, to 5 ...
A 2011 book estimated that a chain of doughnut shops used one billion disposable coffee cups in a year, enough to circle the Earth twice. [10] A 2012 article in OnEarth said that Starbucks used over four billion disposable coffee cups in 2011. [11] The Cup Noodles brand of instant noodles uses expanded polystyrene foam cups to contain the ...
