Plastics Explained

Plastics Explained

PartyPlastics are able to provide an extensive range of high quality disposable, recyclable and unbreakable glasses, all of which are an excellent replacement for real glass.


PLA is 100% compostable and biodegradable. So the cups can be sent to a commercial composting facility with your food waste. There, the cups will biodegrade into compost within 12 weeks.

PLA is suitable for temperatures ranging from -20 to +40°c. So the clear bio-plastic cup is great for cold drinks, smoothies and milkshakes.

Acrylic Plastic

Acrylic is a heavy, reusable rigid plastic. Products made from this product are usually moulded in the Far East for the household market.


Melamine is a thermosetting plastic. It is strong, lightweight and hard, but can be scratched or broken or cracked. It resists acids and alkalies, and most food stains but can be stained. It also stands fairly warm temperatures, but absorbs heat and softens if it gets too hot so cannot be used in microwave ovens. It's used for dinnerware, mixing bowls, laminated counter tops, and other items. Melmac is a common trade name.

Avoid exposure to hot objects, and prolonged exposure to boiling water. Stains may be removed with commercial cleaners made for melamine. Never use scouring powder or any other abrasive.

PET (Polyethylene Terephthalate)

A popular package for food and non-food products. Most commonly used to soft drinks, juice, water and oven ready trays. Manufacturers use PET plastic to package products because of its strength, thermo-stability and transparency. It is also lightweight, resalable, shatter-resistant and recyclable.

Recycled PET (RPET) is environmentally friendly and is easier to recycle than normal plastics because it can be recycled alongside most plastic recycling. It is wear resistant and tolerant to higher temperatures preventing it from cracking under pressure.

Virtually Unbreakable Polycarbonate Plastic Glasses

Polycarbonate plastic glasses are quite simply the toughest, safest plastic glasses on the market. They have an amazingly glass-like feel. They feel substantial in the hand and keep drinks colder longer because of its superior insulating properties. Polycarbonate glasses can be washed up to 500 times in a glass-washer (using a recognised glass detergent such as Finish) without showing signs of degradation. They are heat resistant up to 145 degrees C. Food and Drug Approved.

High Density Polyethylene

Flexible, translucent, waxy and weatherproof. Good low temperature toughness to -60' and good chemical resistance.


Plastic glasses made from polypropylene are disposable, flexible and slightly opaque. Manufactured and packed for maximum hygiene these glasses are a popular choice for large events and festivals. They are cheap and are designed to be used once and then discarded.

Crystal Polystyrene

Plastic glasses made with the same material as CD cases. Disposable glasses will break if dropped onto a hard surface or stood on. Reusable products are fairly tough but will crack if too much pressure is exerted on it. They are made with a thicker, hard walled crystal polystyrene plastic which is dishwasher safe in excess of 100 washes and heat resistant to 100 C.

SAN (Styrene acrylonitrile)

A tough plastic that can take a lot of heavy use but it will break under heavy pressure. These plastic glasses are generally recommended for household or restaurant use. It is glass and dishwasher safe. This plastic can stand temperatures of up to 100 C.
