Why are PET bottles used in packaging?
PET bottles are strong, lightweight, and food-safe, making them ideal for packaging beverages and liquids. At D.E.L.L PET, we manufacture PET bottles that meet strict quality standards while also being fully recyclable, combining performance with sustainability.
PET (Polyethylene Terephthalate) bottles are widely used in packaging—especially for beverages, edible oils, and other liquid consumables—because of a combination of beneficial properties:
1. Excellent Barrier Properties-
Oxygen and carbon dioxide barrier: PET slows gas transfer, helping preserve the carbonation in soft drinks and the freshness of juices or oils.
-
Moisture resistance: It protects contents from external humidity and prevents moisture loss.
-
PET bottles are much lighter than glass but still provide good impact resistance, reducing transportation costs and breakage.
-
Clear PET gives products a clean, attractive look, allowing consumers to see the product inside—important for marketing and consumer trust.
-
PET is inert to many food and beverage ingredients, which helps maintain product safety and integrity.
-
PET is 100% recyclable and widely accepted in recycling streams, making it a relatively eco-friendly plastic option compared to others.
-
It can be blow-molded into various shapes and sizes, offering design flexibility for branding and ergonomics.
-
Compared to glass or metal, PET is cheaper to produce and transport, making it economically viable for mass production.
