A Guide to PET Bottle Blow Moulding

Posted on 20th April 2016

We've been talking a lot about plastics and medical technology in preparation for our trip to Med Tech Innovations 2016 - and we're there right now, on Stand 29! We'll let you know how it all went when we get back, but in the meantime, we're taking a look at another successful area of our business. Could PET bottle blow moulding could be the container manufacturing solution you've been looking for?


The Plastic


Polyethylene Terephthalate (PET) is a non-porous thermosetting plastic that is perfect for manufacturing anything that needs to be water-tight. PET is a popular choice for drinks bottles because it is lightweight, safe and fully recyclable. 


PET Bottle Blow Moulding


The Technique


The PET bottle blow moulding process works by reheating a pre-moulded PET preform which is then automatically positioned into a mould. High pressure food grade compressed air is then injected into the preform which expands to form the shape of the mould. Once the plastic has cooled, the bottle is removed and the process repeats. This process is suitable for making a large range of bottles up to 1 litre in capacity with a range of standard necks available.  Bottles can also be supplied in custom colours with low MOQ's.


Make Your Brand Distinctive


PET bottle blow moulding lends itself to creating a bottle shape that is unique to your brand. You want your bottle to stand out on the shelf - that way it is easily identifiable when it is stood beside your competitors' products in the supermarket. Think how soft drinks manufacturers like Coca-Cola and Orangina have used distinctive bottle shapes to push their brand. Can we help you create a similarly iconic design?


If you need any help with advice about PET bottle blow moulding, please don't hesitate to contact us. We have years of experience in the plastics industry and expanded our bottle blowing capacity last year with a new extrusion blow-moulding machine.
