What is mylar?
Mylar is a British trade name for BoPET(Biaxially-oriented polyethylene terephthalate) a strong polyester film used in packaging, insulation and many other applications.
What are the properties of Polyethylene terephtalate?
Polyethylene terephthalate (sometimes written poly(ethylene terephthalate), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is a thermoplastic polymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications; and engineering resins often in combination with glass fiber. Depending on its processing and thermal history, polyethylene terephthalate may exist both as an amorphous (transparent) and as a semi-crystalline polymer. The semicrystalline material might appear transparent (particle size < 500 nm) or opaque and white (particle size up to a few microns) depending on its crystal structure and particle size.
What are the main 2 uses of PETE polyethylene terephthalate?
Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P), is a thermoplastic polymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications; and engineering resins often in combination with glass fiber.

Is plastic good for making food boxes?
There are many type of plastic available for food boxes, below mentioned is the list of Polyethylene terephthalate (PET or PETE) - GOOD to use High density polyethylene (HDPE) - GOOD to use Polyvinyl chloride (V or PVC) - BAD Low-density polyethylene (LDPE) - OK Polypropylene (PP) - OK Polystyrene (PS) - BAD Other (usually polycarbonate) - BAD For detailed help you can talk to TheCustomBoxes and find the detailed answer.
What are the different types of plastics?
Types of plastic - polyethylene (HDPE or LDPE) found in plastic bags and shampoo bottles - polystyrene (PS) found in computer cases - polypropylene (PP) found in dishwasher safe containers - polyethylene terephthalate (PET) found in soda bottles - polyvinyl chloride (PVC) More generally speaking in engineering, plastics are divided into thermoplastic plastics and thermoset plastics These are based on their properties upon reheating after the plastic is molded. Thermoplastic plastics when heated will melt whereas thermoset plastics will not melt but only burn This is due to the way the branches of polymers coordinate. Thermoplastic plastics governed by largely van der waals forces. Thermoset plastics are crosslinked by covalent bonds
What are the 7 classes of plastic?
The seven types of plastic are: Polyethylene terephthalate, High-density polyethylene, Polyvinyl chloride, Low-density polyethylene, polypropylene, Polystyrene, and an unnamed category consisting of plastics that do not fit into the other categories. Polystyrene is often called Styrofoam.
What does the number on the bottom of recyclable products mean?
It refers to the type of plastic. 1 = polyethylene terephthalate (PET or PETE) 2 = high density polyethylene (HDPE) 3 = polyvinyl chloride (PVC) 4 = low density polyethylene (LDPE) 5 = polypropylene (PP) 6 = polystyrene (PS) 7 = Other

Does alcohol react with plastic?
Yes, alcohol can react with certain types of plastic. Some plastics, such as polyethylene terephthalate (PET) and high-density polyethylene (HDPE), are resistant to alcohol and do not interact with it. However, other types of plastic, such as polyvinyl chloride (PVC) and polystyrene (PS), can be sensitive to alcohol and may degrade or become brittle over time when exposed to it. It is important to consider the type of plastic that is being used when storing or coming into contact with alcohol.
What does mylar mean?
It is a brand name for "biaxially-oriented polyethylene terephthalate (boPET) polyester film" - in other words, a specific type of non-stick plastic designed to be used in hot environments (like a domestic oven).

Is the number a person is looking for on the plastic container inside the triangle or beside it?
The number a person is looking for on a plastic container is located inside the triangle. If you didn't know, the number indicates the type of plastic material used to make that specific bottle. There are varies types of materials 1-7. 1 - PET, polyethlyene terephthalate 2 - HDPE, high-density polyethylene 3 - PVC, polyvinyl chloride 4 - LDPE, low-density polyethylene 5 - PP, polypropylene 6 - PS/PS-E, polystyrene / expanded polystyrene 7 - OTHER, resins or multi-materials
