The Allure of Plastic: A Look at Polypropylene

In previous articles we highlighted the characteristics and applications of polyvinylchloride (PVC) and amorphous polyethylene terephthalate (APET). This month we take a closer look at another versatile plastic, polypropylene.

One of polypropylene’s greatest strengths is its strength. It has traditionally been a substrate of choice in the textile and automotive industries, because it provides excellent impact cushioning and withstands exposure to most chemicals, heat and extreme weather.

More recently, the consumer goods industry has taken notice of this plastic workhorse and its particular applications for confectionery, stationery, food, and cosmetics packaging.

Polypropylene is recyclable, food-safe, and relatively inexpensive compared to other plastic substrates. Although it lacks the glass-like clarity of APET, the advantages of this durable material are clear.

Polypropylene offers a unique combination of usability and aesthetic appeal. It is exceptionally resistant to fatigue, making it ideal for “living hinges” on hair care products, lotion, cosmetics, and other flip-top bottles. Its ability to be cut, creased, and heat scored greatly expands creative design potential for folding cartons.

Polypropylene can be produced clear, clear with colored tints or in solid colors, and can be surface printed, coated, foil stamped or embossed to fulfill almost any custom requirements.

Enhanced consumer-product interaction is made possible by embedding a fragrance directly into the polypropylene compound. This technique is more permanent than using specialty coatings, which tend to dissipate over time. By choosing a customized formula that compliments the product inside, branding is secured and “scents”-ible.

Polypropylene is especially well-suited for:

Food and Confectionery

  • Microwave-ready meals
  • Pudding and dairy products
  • Soup and other liquids
  • Reuseable packaging

    Health and Beauty Products

  • Flip-top bottles
  • Folding cartons
  • Durable displays

    Although polypropylene is manufactured on conventional equipment, its molecular structure requires special care to cut, score and print properly. Choosing a supplier with experience and expertise in converting polypropylene can help turn your plastic packaging ideas into a reality.
