Answer:
If you answered everywhere, you’re probably not far off. This versatile material is in our appliances, computers, clothing, and so much more. Some of the most common places we find plastic is wrapped around the things we buy every day. After all, it’s an effective way to keep food and cosmetics clean and fresh.
But plastic is also lurking in some little known places. When you take a careful look around your home, the sheer number of things you’ll find containing plastic may surprise you.
Food packaging. Cereals, crackers, snacks, and many teas and coffees come in plastic. Most cheese, meat, and yogurt is packed in plastic, as are many condiments.
Milk (including soy and nut milk) cartons. Waxed cardboard contains approximately 20% plastic and 80% paper.
Metal cans are often lined with plastic.
Personal care products. In addition to coming in plastic bottles and tubes, many shampoos, gels, creams, moisturizers, and make up contain synthetic polymers (read: plastic). Some may also contain microbeads.
Dental floss and disposable razors are also often made from plastic base materials.
Synthetic fabrics. Polyester, nylon, rayon, and acrylic yarns and fabrics are all made from plastic. When washed, these materials shed millions of microscopic plastic fibers that eventually wind up in waterways.
Baby wipes and diapers. From their inner layer to their waterproof outer cover, disposable diapers are made from plastic. Super absorbent polymer makes up the absorbent inner core, while the outer layer is usually a petroleum-based plastic or a plastic-treated fabric.
Feminine hygiene products. The average disposable sanitary napkin contains about two grams of plastic.
Wrapping paper is often a mix of plant fibers and laminated plastic. Tape, glitter, and stickers also contain plastic.
Chewing gum. Yes, even gum. One common ingredient included in the “gum base” listed gum labels is polyvinyl acetate.
Cigarette filters contain cellulose acetate, a form of plastic.
Glues, including school glue and wood glue, contain polyvinyl acetate, a type of plastic. The glues used to seal tea bags include polypropelyne, another plastic.
Coffee cups. Even those that appear to be made from paper often have plastic in the lining
