Plastic/acetate packaging offers a lightweight option when deciding what to package your product in. Plastic/acetate doesn’t damage easily and doesn’t need additional protective packaging which makes it perfect when being transported. Plastic holds its shape for longer than alternative materials and can be produced in a wide range of shapes and sizes. Below we have our range of plastics, each with its own detailed description
IS THERE A DIFFERENCE BETWEEN PET, APET, OR PETG?
There is no difference between PET and APET plastic. PET is polyester, which has a chemical name of polyethylene terephthalate. PET can be made with the polymers aligned in two primary ways; amorphous or crystalline. Virtually, all you come in contact with is amorphous with one major exception; microwave food trays which, if made from PET, are made from C-PET (crystallized PET). Essentially all clear PET including Mylar and water bottles are made from A-PET (amorphous PET) and in many cases, the “A” is simply left off.
The Mobius loop recycling symbol for polyester is PET with the number 1, so a lot of people refer to polyester as PET. Others prefer to be more specific, by indicating whether the polyester is crystalline C-PET, amorphous APET, recycled RPET, or glycol modified PETG. These are small variations, intended to ease processing of polyester for the intended end product, whether by injection molding, blow molding, thermoforming, or extruding as well as finishing operations like die cutting.
PETG comes with a much higher price point and is easier to die cut than APET using conventional die cutting equipment. At the same time, it is also softer and scratches much easier than APET. Converters who don’t have proper equipment to die cut APET often work with PETG because of the fact that PETG is softer and scratches easier, so it is usually poly masked (this is a thin “Saran wrap” type covering). This masking needs to be removed from one side during printing, but the masking is usually left on the other side during die cutting to prevent scratching. It is very time consuming and hence more expensive to remove the poly masking, especially if printing a lot of sheets.
There are other subtle differences between PETG and APET, and if you’re not familiar with the benefits and draw backs of how PET is made, remembering the name becomes confusing, but it’s safe to say that all of the above refer to polyester and, from a recycling point of view, they are all treated the same.
