What Make A Good Plastic Resin

Plastic is a type of versatile material that we see every day. The uses of plastic can vary from your food-grade packaging plastic to industrial plastics used for building space rockets. Basically, plastic has made our life more convenient while also allowing us to become more creative and innovative.

Since there is no denying how handy and useful plastic is for all industries today, it begs the question: which type of plastic resin is best? Here are some tips from a plastic resin manufacturer to help you choose the correct plastic resin, depending on your needs:

Polyethylene terephthalate (PET or PETE)

This type of plastic resin is classified as part of the polyester family. Its primary use is for making light-weight food and beverage containers. PET containers are rigid and they can also be used as alcohol or solvent barrier after undergoing additional treatments.

These plastics are impact-resistant, transparent, colorless, and deceptively strong despite being lightweight. Best uses for PET products are cooking oil and soft drink bottles, essential oil bottles, and certain fruit juice containers.

High-Density Polyethylene (HPDE)

This type of plastic is made using petroleum which results in a stronger container with a higher tensile strength. The final product tends to be harder and opaque in nature and has the ability to withstand up to 120 degrees Celsius in temperature, but only for a very short amount of time.

This makes them perfect when used as large distilled water bottles, milk and vinegar bottles, grocery bags, and even liquid detergent or bleach containers.

Polypropylene (PP)

Another commonly used plastic resin for food packaging is polypropylene or PP. It is not as tough as plastic made from HDPE, but it is significantly less brittle. This is an economical choice when made by a plastic resin manufacturer, and can be customized to have an opaque, translucent, any type of color.

Since it has a very high melting point of up to 160 degrees C, it is perfect when used as food containers because it will not melt when filled with hot food in factories or when placed in the dishwasher.

Polystyrene (PS)

Another plastic resin product that is made using petroleum is polystyrene. This is a type of hard and colorless plastic with limited flexibility. The best thing about PS is how it can be cast into any type of mold and it will show all of the fine details once set. PS is commonly used for making bottle caps, straws, and plastic utensils.

Polyvinyl Chloride (PVC)

PVC plastic is considered the third most popular plastic resin type only after PET and PP plastics. It is made of nearly 60% chlorine and requires less petroleum than any other type of plastic in the market. They are very durable and have a very long lifespan, even when exposed to extreme environmental demands.

PVC plastics are usually used for tubing, pipes, spray bottles for chemicals, and pool toys.

Other Plastics

There are other types of plastic resin that a manufacturer can create, depending on your needs. These examples are the most basic and common that can be found just about everywhere. If you have your own specifications, do not hesitate to speak to the manufacturer about your planned uses for the plastics.
