What is PE and PP plastic?

W

Our plastic products such as pallets, crates and paletboxes are made of different types of plastic: HDPE, PE, PP, PO. Some are blue, some are red and some are brown. Choosing between them is not easy. Discover in this article the different characteristics

Plastic pallets and other plastic containers are mainly made from virgin or recycled material. The choice of material will depend on your use and need. A PE pallet will be more impact resistant, especially when used at low temperatures, while a PP pallet will be more effective for use at high temperatures.

If you work in an area where pallets will be in contact with food, it is better to use a virgin HDPE product, such as our H1 hygienic pallet model, rather than another type of plastic. If, on the other hand, you are looking for an economical and environmentally friendly product, recycled plastic pallets are ideal.

In general, the color of the plastic is a good way to know the qualities of a plastic pallet or box. If your container or storage packaging is blue, green, gray or brown, 9 times out of 10 the plastic will be made of virgin material and therefore compatible with food transport. Euronorm E2 plastic crates for the meat industry are an example of hygienic plastic. Most of our plastic food containers, such as the E2 plastic box for meat transport or the foldable palletbox for fruit and vegetables, are colored and suitable for food contact. The plastic containers, some of them in black, are also compatible with foodstuffs.

Which is better polypropylene or plastic?

Polypropylene (PP) is one of the most versatile plastics available. It is a thermoplastic polymer with a wide variety of applications. As a thermoplastic, this type of material can be easily molded by applying heat to the material to achieve the desired shape.

Some of the disadvantages of this plastic are that it can become brittle at low temperatures, sensitive to UV light, less resistant to oxidation or difficult to glue. However, these disadvantages can be improved with the help of additives or elastomers.

At Plásticos Ascaso we are specialists in the injection molding of various plastics, including polypropylene. We are able to create the products that the customer needs. We take care of advising the customer with the mold maker to get the exact piece that he needs, covering sectors as different as the automotive, hotel and catering, gardening, agriculture, etc.

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 rotomolding. 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

Both compounds are polymers, i.e. long chains formed by the repetition of a unit molecule or monomer. From a chemical composition point of view, the difference is that polyethylene is a polymer of ethylene (two carbon atoms and four hydrogen atoms) (CH2-CH2)n; whereas polypropylene is a polymer of propylene (three carbon atoms and six hydrogen atoms) (CH2- CH2-CH2-CH2)n.

Polyethylene is the most widely used plastic in the world and is used to manufacture most of the plastic products around us (shopping bags, detergent containers, gel, cleaning products, etc.).

One of the most frequent uses of polyethylene in our daily lives is in plastic bags. Compared to polypropylene, polyethylene is more resistant to low temperatures, easier to stretch, more flexible and more resistant to wear, abrasion and impact. It is also a cheaper product than polypropylene.

For example, the linear polyethylene of very high density and high molecular weight, HMW-HDPE (high density polyethylene) is used for the manufacture of parts for industrial machinery that require high strength, while branched polyethylene or very low density and low molecular weight, LMW-VLDPE (very low density polyethylene) is used, among other applications, as plastic film.
