Hey there! I'm a supplier of blister white cardboard, and today I'm gonna spill the beans on what raw materials are used to make this stuff. Blister white cardboard is super important in the packaging world, especially for products that need a bit of extra protection and a fancy look. So, let's dive right in!
Wood Pulp: The Foundation
The main raw material for blister white cardboard is wood pulp. It's like the building blocks of the cardboard. There are two main types of wood pulp used: chemical pulp and mechanical pulp.
Chemical pulp is made by treating wood chips with chemicals to break down the lignin, which holds the wood fibers together. This process results in long, strong fibers that give the cardboard its strength and durability. Chemical pulp is usually made from softwood trees like pine and spruce. These trees have long fibers that are great for making high-quality cardboard.
Mechanical pulp, on the other hand, is made by grinding wood chips into fibers. This process is less expensive than chemical pulping, but it also produces shorter fibers. Mechanical pulp is often made from hardwood trees like maple and oak. While it's not as strong as chemical pulp, it can still be used in combination with chemical pulp to make cardboard that's more affordable.
Coating Materials
To make blister white cardboard look nice and shiny, it's usually coated with a layer of material. There are several types of coating materials that can be used, depending on the desired properties of the cardboard.
One common coating material is clay. Clay is a fine-grained mineral that can be applied to the surface of the cardboard to make it smooth and glossy. It also helps to improve the printability of the cardboard, making it easier to add labels and graphics.
Another type of coating material is polyethylene. Polyethylene is a plastic that can be applied to the cardboard to make it waterproof and resistant to moisture. This is especially important for products that need to be protected from the elements, like food and electronics.
Some blister white cardboard is also coated with a layer of wax. Wax can help to make the cardboard more resistant to grease and oil, which is useful for packaging products like fast food and snacks.
Additives
In addition to wood pulp and coating materials, blister white cardboard may also contain a variety of additives. These additives are used to improve the properties of the cardboard and make it more suitable for specific applications.
One common additive is a sizing agent. Sizing agents are used to make the cardboard more resistant to water and ink. They work by filling the pores in the cardboard, preventing water and ink from seeping through.
Another type of additive is a strength enhancer. Strength enhancers are used to improve the strength and stiffness of the cardboard. They can be made from a variety of materials, including polymers and fibers.
Some blister white cardboard may also contain a brightening agent. Brightening agents are used to make the cardboard look whiter and more attractive. They work by absorbing ultraviolet light and re-emitting it as visible light, making the cardboard appear brighter.
