Top Three Packaging Plastics for Your Product

October 10, 2023

When beginning your packaging journey, we recommend that you consider using PET, PE, and PP resin. These three plastics are diverse, recyclable, and easy to work with.

 

1.

PET (Polyethylene Terephthalate): PET is a clear, strong, and lightweight plastic commonly used in the production of beverage bottles, lotion and cream jars, food containers, and polyester fibers. It is known for its excellent barrier properties, meaning it can effectively prevent the permeation of gases and liquids. PET is recyclable and commonly identified with the resin code "1" within the recycling symbol.

 

This plastic also comes in a variety of colors and opacities. PET is naturally clear, but it can also easily be tinted – popular translucent colors include amber, blue, and green. It can also be opaquely colors – popular opaque colors include white and black. Whatever color you need, PET can accommodate!

2.

PE (Polyethylene): Polyethylene is a versatile and widely used plastic that comes in different forms, such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE). HDPE is a tough and rigid plastic commonly used in milk jugs, detergent bottles, and plastic bags. LDPE, on the other hand, is more flexible and is often used in packaging materials, squeeze bottles, and plastic wraps. Polyethylene is recyclable and is typically identified with the resin code "2."

 

In its natural state, PE is a cloudy translucent color. PE commonly has a matte or satin finish. It can come in colors of white, black, natural, or any opaque color options you like.

 

3.

PP (Polypropylene): Polypropylene is a durable and heat-resistant plastic commonly used in various applications, including food containers, automotive parts, and packaging materials. Most plastic packaging lids are made from PP. It has a high melting point, which makes it suitable for products that require heat resistance. PP is recyclable and is typically identified with the resin code "5."

 

It is available in any color, though the most common colors are white, black, and natural.

 

In summary, PET is commonly used for packaging and has good barrier properties. PE comes in different forms, with HDPE being rigid and strong, while LDPE is flexible and lightweight. PP is a versatile plastic with high heat and chemical resistance. Each of these plastics has specific properties that make them suitable for different applications.
