What is the difference between PET and PP plastic?

Pet and plastic

There are different types of strapping in the industry, among which polyester (PET) and polypropylene (PP) strapping stand out. Each of them has different characteristics and uses, so it is essential to know their differences and advantages, and take them into consideration before choosing one or the other.

Both polypropylene and polyester are two essential polymers for the manufacture of different plastic products that may sometimes appear to be similar compounds, but in reality their differences are quite notable.

Polyester strapping (PET) is composed of a very resistant fiber that is used for strapping different materials. For this reason, and thanks to its high performance and care of the load, it is fast becoming the most requested packaging system by industries.

The combination of all these advantages makes polyester strapping (PET) the most widely used material in the world to compact and secure the storage and transport of goods in an efficient way.

Monomers are the building blocks of the structure of plastics (e.g. ethylene). They are simple molecules (carbon and hydrogen). The union of many monomers constitutes a polymer (e.g. polyethylene).

It is produced through terephthalic acid and ethylene glycol by polycondensation. There are two types: textile grade and bottle grade, for bottle grade it must be post-condensed, and there are different colors for these uses.

It is a thermoplastic manufactured from ethylene (made from ethane, one of the components of natural gas). It is very versatile and can be transformed in different ways: injection, blow molding, extrusion or rotational molding.

It is produced from natural gas. Like HDPE, it is highly versatile and can be processed in different ways: injection, extrusion, blow molding and rotational molding. Its transparency, flexibility and economy make it present in a variety of containers, alone or in conjunction with other materials and in a variety of applications. Advantages

How to differentiate pet from pvc

Cardboard, glass, paper, wood, fabric, cork… packaging can be made of many materials, but plastic is probably the most popular. And the fact is that the petroleum derivative offers endless alternatives that meet the needs of producers, customers and the product itself. Among them there are two that have achieved by their own merits that we remember them by name, we are talking about PET or polyethylene and PVC or polyvinyl chloride. Do you know how to distinguish between them? PET or PVC? when to use each one?

As a packaging company, when we develop a plastic container, we usually end up making that decision. The customer wants the material that offers the most advantages, but each product – and each packaging – is different.

Among the plastic materials we use to manufacture our products is PET (polyethylene terephthalate), widely used in many sectors, which offers a very important property: it is 100% recyclable, which leads us directly to RPET, which is recycled PET plastic.

Containers made of PET are widely used in the food, cosmetics and pharmaceutical sectors, and we can see them in the form of blister packs to present and protect a large number of items, such as electronic or DIY products, among others.

It should be clarified that PET plastic can be virgin (first use) in this case it is called APET, or contain between 10 – 20% of virgin material on the outside, the rest of the material coming from recycled material known as PET ABA.

With the passage of time and technological advances, it is possible to use RPET for food use and many more applications, thanks to a complex process that decontaminates and confers properties to the plastic that improve it notably. Moreover, again at the end of its life, RPET can be recovered for a new life.
