Preforms are produced from polyethylene terephthalate (PET), so they are known as Bottle Seal Liners. They are produced by RETAL utilizing a highly-accurate injection molding process on equipment from the leading world suppliers.

Preform weight is dependent upon the conclusion container’s preferred volume. Preforms can be solitary-coating or multilayer. Buffer preforms offer additional benefits and improved drink shelf-life, due to an exclusive coating a part of a number of layers of polyethylene terephthalate.

RETAL provides a full range of polyethylene terephthalate (PET) preforms for packaging, moving and storing drinking water, nutrient water, carbonated drinks, fruit juices, nectars, infant meals, milk products, dark beer, reduced-alcohol and alcoholic beverages as much as 40% abv, edible oil, mayonnaise, ketchup, sauces, household and makeup products products

In addition to standard preforms, RETAL companies custom preforms customized to individual consumer requirements.

To find the best packaging choice for your needs, talk to a sales representative or tech support professional. They will help you create a suitable selection based on your equipment, the intricacy of the model of the PET bottle, along with your unique requirements.

PET preforms, better known as “preforms”, are an intermediate product whereby the manufacture of bottles is achieved. The nickname of PET is because of the content that they may be made, polyethylene terephthalate.


The product is created through a precision blow molding and shot procedure. The preform PET is injected in to a mold to become preform that, with an extra blowing step, will require the desired form (mainly storage containers for drinks, detergents or any liquid).

One of the advantages of PE Foil Sealing Liner is the great flexibility when it comes to style, since very different products can be created via this same process. Depending on the client’s requirements, we can differ the weight, volume, colour, form or throat from the bottle.

PET preforms can be utilized for that packaging of nutrient water, juices, liquors, soft drinks, carbonated drinks, oils ideal for consumption, medicines, pickles, jams, customer products, and so on.

Two various kinds of systems can be used, which are:

Single Stage or Integrated System

The shot and blowing processes are incorporated within the same machine. The preform is shot molded and while it is still hot it is blown to create the part. This method is suitable for small and medium creation outlines.

Two Phase System

In this method, two individual machines are utilized, a machine for the injection from the preforms and another for blowing to reheat the preforms to make the last item. This process is most effective for method and enormous-scale production.


* Drying of the Pet (granules)

* Plasticization of PET

* Injection molding from the preform

* Home heating the preform

* Blow molding of the preform

* Cooling and expulsion of the final item

Regular proformas

Inspite of the great malleability with this product, there are some standards in order to simplify the process. A number of the specifications we offer from PCO, POPP, Bericap, BPF, OIL

In order to have an effective production of preforms it is actually essential to rely on an associate who invests in research and development to offer innovative and flexible options both for machines and for moulds.

In a production procedure the systems that can change lives, for example, are the ones optimising the injection unit, the press device as well as the moulds.

The injection device will need to have qualities for instance a servo drive, continuous rotation of the attach at low speed, the opportunity to use up to 4% colouring representative without having a drop in stream and to produce different extrusion sizes, the injection system with minimal lack of plasticization capability.

For high overall performance, the press device should have Bottle Preform, guarantee excellent cleaning, long working life and minimum maintenance costs.

The moulds should be designed so that the preforms are of top quality and creation is fast, they have to have decreased upkeep costs, a wear-evidence coating, excellent neck cooling systems.

Also, extra advantages are given by the ability to choose moulds kswpvl up to 144 tooth decay that can be tailored to machines created by the main manufacturers on the market.

Machines with injection-compression system should have components that will make the entire procedure much better and more economical, as an example: optimized plasticization attach with continuous rotation to reduce consumption and AA amounts, ability to consume to completely rPET without creating modifications, rotating injection-pressure tire with decreased cavity tonnage which allows less put on in the form.

Machines with technological characteristics like the types outlined create a considerable decline in TCO, make operator jobs more secure and simpler, and also a made the decision effect on the quality of the preform and also the working lifetime of the moulds.
