Food & Beverage Packaging

Did you know that cellophane wrap has been around the kitchen since the early 1900s? It was an innovation in food and beverage production as the first, fully flexible, water-impermeable wrap. Since then, packaging for food and beverages has played an integral role in smart packaging solutions. The main reason for plastics in food and beverage applications is for protection and increased shelf-life of your munchies. Other properties include the following:

  • Clarity
  • Withstands extreme temperatures
  • Moisture resistant
  • Chemical resistant
  • Durable
  • FDA approved for food and beverage contact
  • Economical

Plastic packaging allows for airtight freshness, keeps edibles safe and sanitized, freezer safe, and safely ships products from farm-to-table. Among its many applications including bottles, bags, containers, tableware, and wrapping.

Consumer Packaged Goods

Due to the versatility of plastics and the variety of polymers available, consumer packaged goods take many shapes and forms. This variety allows brands and businesses to set their product apart on the shelf. Additionally, plastic packaging can be molded and formed to increase the amount of product available to the consumer while decreasing packaging. Thus, plastic packaging conserves resources and provides efficiency. Other properties include:

  • Lightweight
  • Strong & durable
  • Different processing techniques: mold, extrusion, cast, blown
  • Cosmetic looks: color, weight, size, shape, utility, printing, protection
  • Design versatility

Cosmetic & Personal Care Packaging

There is no industry that values design and functionality more than the cosmetics industry. With plastic packaging, these industries have limitless options for containing and distributing their products and materials. It is also important to note that plastics for cosmetics are highly chemical resistant. They are formulated to maintain the integrity of material as well as not disintegrate with contact. That is the beauty of polymers. Other properties include the following:

  • Durable
  • Good tensile strength
  • Single-use for less contamination
  • Design efficiency and diversity
  • Lightweight
  • Safe and secure delivery from shelf to consumer
  • Improved shelf-life
  • Flexible

Cosmetic packaging needs to be compact, portable, and shatter-proof for everyday wear and tear. Plastic packaging fits the bill perfectly and includes items like perfumes, lotions, lipsticks, cosmetic chemicals, shampoos, conditioners, and so on.

Home & Garden

Garden fertilizers, laundry detergent, cleaning supplies—take a walk through your house and you will find plastic packaging providing safe, secure, and convenient storage for your everyday needs. Lightweight, yet durable is the key to these packaging formulations. They don’t let the integrity of the chemicals degrade, but they keep their shape as well, even in harsh environments with exposure to even harsher chemicals. Top properties for polymers used for household packaging include:

  • Shatter-proof
  • Efficient designs
  • Chemical resistant
  • Moisture resistant
  • Flexible

Plastic packaging for household use is critical for withstanding harsh environments while maintaining the integrity of the material. Some applications include concrete, fertilizer, soil, cleaning products, gardening pots, containers, laundry detergents, and more.

Common Packaging Polymers & Amco's Top Suppliers

As the demand for plastic packaging expands and industries look for alternative methods for safe, efficient, economical packaging, we are ready to provide polymer solutions with our vast network of supplier relationships.

Below we discuss some of the top polymers used for packaging, their uses, and our main suppliers for these materials.



As one of the most widely used plastics, HDPE (High-Density Polyethylene) makes many types of bottles and containers. Unpigmented bottles are translucent, have good barrier properties and stiffness, and are well suited to packaging products with a short shelf life such as milk. Because HDPE has good chemical resistance, it is used for packaging many household and industrial chemicals such as detergents and bleach. Pigmented HDPE bottles have better stress crack resistance than unpigmented HDPE.


  • Excellent resistance to most solvents
  • Higher tensile strength compared to other forms of polyethylene
  • Relatively stiff material with useful temperature capabilities

Common Packaging Applications

  • Bottles for milk, water, juice, cosmetics, shampoo, dish and laundry detergents, and household cleaners
  • Bags for groceries and retail purchases
  • Cereal box liners


While it is slightly less durable than HDPE, LDPE still displays excellent toughness, flexibility, and transparency. This makes it a great candidate for film applications and where heat sealing is necessary. LDPE also is used to manufacture some flexible lids and bottles as well as in wire and cable applications.


  • Excellent resistance to acids, bases, and vegetable oils
  • Toughness, flexibility, and relative transparency; good combination of properties for packaging applications requiring heat-sealing

Common Packaging Applications

  • Bags for dry cleaning, newspapers, bread, frozen foods, fresh produce, and household garbage
  • Shrinkwrap and stretch film
  • Coatings for paper milk cartons and hot and cold beverage cups
  • Container lids
  • Squeezable bottles (e.g., honey and mustard)
