Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
Paper straws are in demand as a sustainable alternative to plastic straws, and they are made by a different manufacturing process. Plastic straws are typically made from polypropylene, but paper straws are made from layers of food-grade paper bonded together with water-based or hot melt adhesives, using gum powder and packing materials.

Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English fiber) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos ...
Paper converting is required for the manufacture of nearly all paper based products, such as magazines, books, newspapers, labels, bags, and general purpose paper products. [ 8 ] The process of processing pre-cut cartons or "blanks" and folding them into the appropriate shape to become finished packaging containers is known as tray forming or ...
Handmade paper is also prepared in laboratories to study papermaking and in paper mills to check the quality of the production process. The "handsheets" made according to TAPPI Standard T 205 [ 20 ] are circular sheets 15.9 cm (6.25 in) in diameter and are tested for paper characteristics such as brightness, strength and degree of sizing .

Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be ...
