PET preforms, better known as “preforms”, are an intermediate product through which the manufacture of bottles is achieved. The nickname PET is due to the material from which they are made, polyethylene terephthalate.

This product is created through a high-precision blow molding and injection blow molding process. The molten PET is injected into a mold to become a preform which, through an additional blowing stage, will take the desired shape (mainly containers for beverages, detergents or any liquid).

Gestión de Compras has extensive experience in the design, development and manufacture of plastic blow molds. We also offer a complete solution, developing injection molds for PET preforms and caps.

Features of PET preforms

One of the advantages of PET preforms is their great flexibility in terms of design, since very different products can be created through this same process. Depending on the customer’s needs. The weight, volume, color, shape or neck of the bottle can be varied. Other characteristics of the material are listed below:

  • In addition, it is a highly flexible material and can be used for different types of packaging and is also extremely resistant. Unlike glass, it falls and does not break.
  • It is considered to be the most sustainable material on earth. In fact, among plastics it is considered number one because it is infinitely recyclable.
  • It is highly cost-effective.

PET preforms can be used for the packaging of mineral water, juices, liquors, soft drinks, carbonated beverages, edible oils, medicines, pickles, jams, consumer products, etc.

However, more and more manufacturers and consumers are changing their materials, processes, etc., adapting them to current market needs. Nowadays, the manufacture of PET containers based on preforms is undergoing a very rapid evolution, due to the new trends and technologies available.

In addition, manufacturers are switching from alternative materials to start using PET. This is due to the great flexibility provided by the material, which is able to adapt to existing requirements and needs. On the other hand, this material is extremely cost-effective due to the incorporation of higher and higher percentages of recycled content.

We always complement the manufacturing process with the “Intravis” quality control system. Our PET preforms also meet all food safety, environmental and quality requirements.
