Preforms are made using a moulding process. The molten polymer is injected into a mould to create the preform that, through blow moulding, will take on the appearance of the bottle that it is destined to be.

Each preform is formed of a finish, that is the neck of the bottle, that is never modified at the blow moulding stage. The diameter and thread type of the finish are the characterising elements of the preform and determine the possibility of screwing it to any type of cap. The tubular structure that forms the neck of the bottle during blowing determines the weight of the final product. The diameter, length and shape of the body are the most important elements that give the blown container its final characteristics. The PET polymer does not have a colour of its own, but can take on different colour tones when correctly treated and mixed with coloured additives.

The professionalism of Valgroup’s staff and the use of state-of-the-art moulding equipment enable our company to produce optimal preforms for any type of bottle, from half-litre “first price” bottles with light packaging to preforms for HO.RE.CA.

Thanks to our close collaboration with plant and colour manufacturers, we can develop dedicated, tailor-made projects in a very short time and supply a quantity of preforms to allow clients to carry out a meaningful trial run before making any final decisions.

The choice of top quality virgin and recycled material and rigorous monitoring of our laboratories are a significant guarantee of the functionality of our products. The label stuck on each octabin (packaging solutions to transport loose goods) contains all the information about the materials used, the production time and the quality control officer, and ensures complete traceability of the contents.
