For any business considering plastic manufacturers for their production process, there is a little bit they need to know about plastics, otherwise they might end up with a material that simply is not going to work for the services they require. While the plastic manufacturers are able to help them with some of the information they do not understand, it is always a good idea to seek out education before going into a potential meeting with the plastic manufacturers. Due to this, by simply knowing the plastics and available material, it is possible to go into the meeting with all of the knowledge someone needs.
Polyethylene Terephthalate
This is known as a Code 1, but most people might see it referred to as Pet or PETE. This is an extremely thin plastic that is typically used in bottled water or other not pressurized cooking and food ingredients. One thing to take into consideration is that this plastic is fine for a single use, but it is not designed for multiple uses or to be heated. Keep this in mind when shopping around for potential plastics.
High-Density Polyethylene
Also known as Code 2 or HDPE, this is a thicker version of Code 1. It also has more of an opaque look to it and is typically used in plastic jugs, such as water or milk jugs. It is also used in motor oil containers, shampoo bottles and some toys.
Polyvinyl Chloride
While it is Code 3, you probably know it better as PVC
PVC is used for all sorts of material, ranging from squeeze bottles to cling raps and even bibs. It has been occasionally linked to reproductive problems, so when selling anything that has to do with this, it is best to avoid Code 3 plastics.
Low-Density Polyethylene
Code 4 or LDPE is good if a company is producing grocery bags, plastic wraps or other, similar products. It is also an extremely safe plastic.
Polypropylene
Code 5 or PP, it is a flexible yet hard plastic found in ice cream containers. If someone manufacturers food products, this is an excellent option.
Polystyrene
Code 6 or PS, it is the same plastic plastic spoons and forks are manufactured from.
Polycarbonate/Nylon/Acrylic
All of these fall under Code 7, so make sure the manufacturer clarifies the kind of material they use for their Code 7. These can also be acid resistant at times.
