Understanding 5 Common Plastics Used in Food Packaging

TEMPO.CO, Jakarta - Plastic packaging has become ubiquitous in the food industry due to its convenience, durability, and cost-effectiveness. Its resistance to pressure, impact, and contamination makes it ideal for preserving food quality and safety. Moreover, the material's flexibility allows for packaging to suit various food products and conditions.

However, the environmental consequences of improper plastic waste management are significant. To mitigate these issues, there is a growing emphasis on developing environmentally friendly plastics and implementing effective waste management strategies.

Types of Plastic

Read on to better understand the common types of plastic used in food packaging:

1. Polyethylene (PE)

The most widely used plastic for food packaging is PE which comes in two primary forms: HDPE and LDPE. HDPE is rigid and ideal for milk and water bottles, while LDPE is flexible and suitable for food wraps and protective layers. PE offers excellent water and vapor resistance and durability.

2. Polypropylene (PP)

Known for its heat resistance, PP is commonly used for microwave-safe containers, bottles, caps, and snack packs. It is stiffer than PE, making it a suitable choice for these applications.

3. Polystyrene (PS)

Often used for disposable food ware, such as plates, cups, and lunch boxes, PS comes in two forms: rigid (common PS) and expanded (EPS or styrofoam). EPS provides insulation for temperature-sensitive foods.

4. Polyvinyl Chloride (PVC)

This flexible plastic is used for food packaging, such as bread wraps and certain bottle caps. Its transparency and flexibility make it suitable for soft drink bottles as well.

5. Polyethylene Terephthalate (PET)

PET is a strong, lightweight, and transparent plastic ideal for packaging salads, fruits, carbonated drinks, and water. Its chemical resistance adds to its appeal.

While plastic is essential to the food industry, its environmental impact necessitates careful management. Recycling is crucial in reducing plastic waste, particularly for PE, PP, and PET. 

Moreover, food manufacturers should prioritize environmentally friendly and recyclable packaging options and educate consumers about proper waste disposal. By collaborating, industry, government, and the public can significantly improve plastic waste management and minimize the adverse impact of plastic packaging on the environment.
