Guide to Thermoforming Plastics in Packaging
Thermoforming is a critical process in the manufacturing of diverse products, especially prominent in the packaging industry. This guide offers a detailed examination of the key thermoforming plastics, focusing on their properties, applications, and sustainability efforts to guide manufacturers in selecting the most appropriate materials for their needs.
Key Thermoforming Plastics and Their Applications
Polyethylene Terephthalate (PET) and PETG
- Properties: PET is highly resistant to environmental factors, while PETG offers excellent clarity and impact strength.
- Applications: Both are used extensively in food and beverage containers, with PETG also favored in medical packaging due to its ease of forming and sealing.
Polypropylene (PP)
- Properties: Chemical-
resistant, rigid, with good impact strength and temperature resilience. - Applications: PP is ideal for consumer packaging, especially food containers that require microwave and dishwasher safety.
- Properties: Chemical-
High Impact Polystyrene (HIPS)
- Properties: Offers good impact strength and rigidity, suitable for vacuum forming.
- Applications: Essential in packaging for food, medical trays, and as electrical insulation.
Polyvinyl Chloride (PVC)
- Properties: Versatile, offering excellent chemical resistance and a range from flexible to rigid.
- Applications: Used in transparent packaging, medical tubing, and blister packs, adaptable for clear or opaque products.
