Varieties of Plastic Bottles – Bottles Jars and Tubes Inc.

Which type of plastic bottles best suit your business? Keep reading and you’ll learn about the different plastics used to make our products.

Plastic was invented in the late 1800’s and by 1946, Tupperware, spray bottles and other plastic squeeze bottles were exploding onto the American market. Plastic bottles were being used for anything and everything and still are today. In fact, plastic specialty bottles are a necessity for many companies in order to offer their product to customers in a convenient, user-friendly way. But as a business owner, how do you know which type of plastic is best suited for your product?

Bottles Jars and Tubes Inc. offers a variety of plastic bottles made with several different kinds of plastic:

  • Polyethylene (high, medium and low density)
  • Polypropylene
  • Polyethylene Terephthalate (PET)

To most of us, those names mean basically nothing. But when it comes to the packaging of food or health products, it’s vital for business owners to know which of these kinds of plastics can safely and best contain their product. So let’s dig in and get to know these plastics a little better.

High, Medium and Low density Polyethylene

Polyethylene is the most common kind of plastic with an annual global production of around 80 million tons. This type of plastic is defined by Merriam Webster as “any of various lightweight thermoplastics (CH2CH2)x that are resistant to chemicals and moisture and are used especially in packaging, insulation, surgical implants, prostheses, and tubing.” It’s commonly used for things like food containers, plastic bottles and plastic bags. Durable, lightweight and flexible, Polyethylene is a popular choice for many companies in the market for specialty bottles, plastic squeeze bottles and similar products. Bottles Jars and Tubes Inc. offers high, medium and low density Polyethylene plastic bottles to meet a variety of different needs. High density Polyethylene is more dense and less permeable than low density Polyethylene. Medium density Polyethylene offers higher resistance against cracking.

Polypropylene

Polypropylene is also a widely used plastic with a variety of applications including reusable containers, ropes, labeling and lab products. It’s a very versatile product with a melting point of 320 degrees Fahrenheit, which makes it ideal for food containers. Polypropylene is nearly shatterproof, lightweight, and it doesn’t absorb water. Business owners who are wanting to customize plastic bottles or specialty bottles will be happy to hear that Polypropylene is extremely easy to customize with labeling and/or color. Additionally, any color or labeling added to specialty bottles will not sacrifice the quality and durability of the Polypropylene.

Polyethylene Terephthalate (PET)

Polyethylene Terephthalate, or PET, is another strong and durable plastic. The most common member of the Polyester family, PET is safe for consumer products like food and cosmetics. It’s also recyclable, transparent and lightweight. PET is a great choice for an environmentally-friendly company that wants to encourage the recycling of their products. For example, plastic bottles made with PET can be recycled and reused to manufacture various items like clothes, sheet packaging, bags and even car parts. This type of plastic is globally recognized as being a safe plastic for medical use as well, so lab products such as pharmacy vials and lab tubes are often made with PET.
