Blow Moulding

Blow Moulding

Manufacturing process used in-house to produce our range of plastic bottles. Our machines are capable of manufacturing bottles with volume capabilities ranging from 20ml to 4 Litres. We have a range of stock moulds available, or you can use your own custom moulds. All bottles manufactured on-site are made with the plastics material Polyethylene in High density or Low density. All materials used are food grade approved and certified by our suppliers and are recyclable. 

High Density Polyethylene (HDPE) 

HDPE has a large strength to density ratio, making it a popular choice for bottle as this makes it generally quite rigid and very resistant to breakage. The surface appearance of HDPE is a matte waxy look, and it is hard to semi flexible to the touch. Withstanding high temepratures of up to 75°C without softening and resisting temperatures as low as -75°C without becoming brittle.

HDPE is moistureproof, making it ideal for storing liquids, yet breathable to allow the flow of oxygen through the material. In addition, it is generally resistant to chemicals and unaffected by most food acids and hosehold solvents. 

Low Density Polyethylene (LDPE)

LDPE has the same general properties as HDPE; but because it has a lower density compared to HDPE, it is softer and more flexible, resulting in bottles being more 'squeezable', sightly more translucent and scratches more easily. Like HDPE it easily resists water and chemicals and has a good impact strength. LDPE is able to withstand much lower temperatures than HDPE, being able to maintain its strength and flexibility at sub-zero temperatures; however it cannot endure as high temperatures as HDPE and will start softening at 70°C.
