Air pillows are plastic bags filled with air, used to cushion items during shipping. They are lightweight, non-abrasive, and immobilize products within a box, protecting them from damage. Air pillows are often made from recyclable or biodegradable materials, but they have come under scrutiny for contributing to plastic pollution. Companies like Amazon are replacing plastic air pillows with paper alternatives, which are cheaper and provide equal or better protection. Other types of plastic pillow packaging include Polypropylene, which is strong, clear, and used for cosmetics and snacks, and Polyethylene, which is suitable for food items.

What You'll Learn
Polypropylene bags are tear-resistant and durable
Polypropylene is a popular choice for plastic pillow packaging. Its qualities of durability, flexibility, and resistance to moisture make it ideal for protecting pillows. Polypropylene bags are tear-resistant and sturdy, providing a good balance between flexibility and durability. This makes them suitable for the long-term storage and transportation of pillows.
Polypropylene's higher tensile strength compared to other plastics like PET and PVC is a significant advantage. Its good heat resistance and chemical resistance further add to its durability. The material's tear-resistance ensures that pillows remain tightly protected and in good condition during shipping and storage.
Polypropylene packaging can also provide a professional and stylish look for decorative pillows or luxury items. The design of the packaging plays a vital role in both functionality and aesthetics. The use of appealing colours and graphics, and informative content can enhance the overall presentation of the pillow product.
Additionally, polypropylene bags are versatile and can be formed on a vertical form, fill, and seal (VFFS) packaging line at relatively high speeds. This makes them economical and efficient for mass production.
While polypropylene is a popular choice, other materials like polyethylene (PE) and PVC are also commonly used for pillow packaging. PE comes in low-density (LDPE) and high-density (HDPE) forms, offering durability and flexibility. HDPE, in particular, is known for its rigidity and durability, making it suitable for protecting products during shipping.

Eco-friendly alternatives include biodegradable plastic
Plastic packing pillows are typically made from polyethylene, polypropylene, or PVC. However, as consumers become increasingly concerned about sustainability, eco-friendly alternatives are gaining traction. These alternatives include biodegradable plastic, which helps reduce the environmental footprint and contributes to a circular economy. Here are some specific examples of eco-friendly alternatives to plastic packing pillows:
Biodegradable Materials: Biodegradable packing peanuts, for instance, are made from natural, non-toxic sources like wheat or corn starch. These materials offer the same level of protection as standard packing materials but are environmentally friendly.
Recycled Paper Filler: Amazon, for example, has replaced plastic air pillows with 100% recycled paper filler, which is recyclable, offering better protection to products and making it easier for customers to recycle.
Inflatable Air Pillows: Inflatable air pillows made from 100% recycled materials are another eco-friendly alternative. They can be reused, recycled, and are biodegradable, providing an excellent option for filling voids in boxes or cushioning packed items.
Natural Fibers: Natural fibers such as organic cotton, wool, and latex are also used for eco-friendly pillows. Companies like Holy Lamb Organics use eco-wool sourced through sustainable practices, supporting small sheep farmers. Other brands offer pillows made from organic cotton and natural fibers, providing hypoallergenic and breathable options.
Milk Plastic: Milk plastic is another viable alternative to traditional plastic packaging. It is made from milk protein, is water-soluble, and is biodegradable due to its casein molecules.
These examples demonstrate a growing trend towards environmentally conscious choices in the world of packing pillows and beyond. By adopting eco-friendly alternatives, businesses can enhance their reputation, meet consumer demands for sustainability, and contribute to a greener planet.

HDPE film is recyclable and rigid
Plastic air pillows have been widely used in packaging, including for pillows, but companies such as Amazon are now replacing them with paper fillers due to environmental concerns. Polyethylene is one of the most common materials used for pillow packaging due to its durability and flexibility. It comes in two forms: low-density polyethylene (LDPE) and high-density polyethylene (HDPE).
The HDPE reclamation process involves water and agitation. Paper that detaches from the container becomes pulp, which does not sink but remains suspended in the liquid, adding load to the filtering and water treatment systems. Paper that remains adhered to the HDPE travels with it to the extruder, where the material carbonizes and causes colour defects. Even after melt filtering, the burned smell and discolouration remain with the recycled HDPE, negatively affecting its potential reuse.
During the recycling process, inks used in direct printing may bleed or discolour the HDPE or introduce incompatible contaminants that reduce the value of the recycled product. If inks redeposit on natural HDPE flake, this discolouration may diminish its value for recycling. It is desirable for labels to float so that they can be recovered for recycling. However, with natural HDPE, the label can discolour the wash water and the flake, and must be tested.
Polyolefin labels are commonly expected to be PP films or PE film and are compatible with the coloured and natural HDPE recycling stream. However, given the natural HDPE stream is sensitive to discolouration, thorough label testing is required to determine the impact.

Paper filler is a sustainable alternative
Plastic air pillows have long been used as a protective packaging solution, but they are detrimental to the environment, contributing to plastic pollution and endangering wildlife. As consumers become increasingly concerned about sustainability, companies are seeking eco-friendly alternatives. Paper filler is one such alternative that is not only sustainable but also effective in protecting products during shipping.
Paper filler, made from 100% recycled content, is recyclable and compostable. It offers excellent shock absorption, protecting sensitive products from breakage during transit. This makes it a more sustainable option than plastic alternatives, which can be harmful to the environment if not disposed of properly.
The use of paper filler as a packaging solution has gained traction, with companies like Amazon transitioning from plastic air pillows to paper filler. Amazon has replaced 95% of plastic air pillows in North American delivery packaging with paper filler, with the goal of completely removing plastic air pillows by the end of the year. This move has been praised by environmental groups, as it significantly reduces plastic pollution and contributes to a circular economy.
In addition to its sustainability benefits, paper filler can also enhance the unboxing experience for customers. Tissue paper, for example, can be customized with colours and graphics, boosting the quality and value perception of the product. It can also be used to wrap individual products, providing corner and edge protection while creating a memorable unboxing experience.
For companies seeking sustainable and eco-friendly packaging solutions, paper filler is a viable option. It offers the same, if not better, protection for products during shipping and is more environmentally friendly than plastic alternatives. By adopting paper filler, companies can not only meet the demands of environmentally conscious consumers but also play a part in reducing plastic pollution and protecting our planet.
