Plastic covers are used to protect various items, such as books, magazines, and papers. In the printing industry, a thin plastic film covering one side of the paper is called C1S (Coated, 1 Side). Plastic covers for books and magazines are sometimes referred to as cellophane wrappers or plastic sleeves. In the construction industry, plastic sheeting is used to protect surfaces during work, and it can have various properties such as UV protection or self-adhesion.

What You'll Learn
Coated paper or coated cover stock
In the printing industry, paper coated in a thin film of plastic on one side is referred to as "C1S" (Coated, 1 Side). Coated paper stock has a matte or glossy finish and is usually smooth with a slight shine, sometimes even a high shine. The coating makes the colours on the paper appear brighter and more vibrant. This is because coated stock absorbs less ink than uncoated paper, allowing the ink to stay on top of the paper, resulting in sharp and crisp images.
Coated paper is widely used by photographers, restaurants, designers, and artists as it showcases their images in the best possible light. In addition to matte and gloss finishes, specialty stocks are available with silk and velvet finishes. Coated paper is also advantageous due to its impressive resistance to wear and tear, water, and dirt, ensuring that printed materials remain crisp and professional for longer.
On the other hand, uncoated paper has a more natural, earthy, or organic look. It is very absorbent, making it ideal for printing forms and materials that need to be written on, such as envelopes, letterheads, student workbooks, and novels. Uncoated paper is also excellent for creating printed materials with special effects like foil stamping, as the higher contrast makes the foil stand out more.
When deciding between coated and uncoated paper, it is important to consider the desired appearance, functionality, and intended use of the final product. Coated paper is ideal for showcasing images and ensuring durability, while uncoated paper provides a more natural look and is better suited for writing or special printing effects.

Plastic sheet protectors
Sheet protectors are available in various sizes, such as letter size (8.5" x 11") and can be purchased in packs of different quantities, like 25 or 50 sheets. They are designed to fit into standard binders and clipboards, making them convenient for organisation and transport. The protectors are also lightweight, making it possible to fit more pages into a binder without adding significant bulk.
The protectors are usually made from durable vinyl or polypropylene, ensuring that documents remain secure and protected. Some sheet protectors feature an electrostatic welding process along the seams, providing an even stronger and more uniform seal. This helps ensure that documents are fully protected from external elements.
Sheet protectors are highly versatile and can be used for a range of applications. For example, they are ideal for genealogy documents, instruction manuals, magazine articles, and scrapbooking. They are also useful for medical records, as they help keep critical information protected and easily accessible. Additionally, some sheet protectors offer a non-glare or anti-glare option, enhancing readability under different lighting conditions.
Overall, plastic sheet protectors provide an affordable and effective solution for preserving and organising important documents, making them a popular choice for individuals and businesses alike.

Plastic sleeves
The use of plastic sleeves offers protection and durability to paper products, making them ideal for long-term use and storage. They are particularly useful for documents that need to be kept clean and free of moisture damage, as the plastic creates a barrier that prevents liquids from penetrating and damaging the paper.
In addition to their practical benefits, plastic sleeves can also enhance the appearance of paper products. They provide a smooth, glossy finish that gives documents a professional and polished look. This feature is especially advantageous for presentations, reports, and marketing materials where visual appeal is important.

Plastic wallets
In addition to the traditional plastic document wallets, there are also paper document wallets available. These wallets are designed to be attached to the outside of packages and provide a sustainable alternative to plastic. They are made from 100% paper and feature a self-adhesive backing, allowing them to be easily stuck onto boxes and parcels. The top layer of these paper wallets is translucent, allowing the contents to be easily read, and features a glazed coating that protects against water damage and weathering during transit.
When choosing between plastic and paper document wallets, it is important to consider the specific needs and preferences. Plastic wallets offer a durable and long-lasting option, while paper wallets provide a more environmentally-friendly and recyclable alternative. Additionally, the choice between the two options may depend on factors such as cost, availability, and the level of protection required.

Paper laminated with heat
Lamination is the process of sealing paper between sheets of plastic using heat and adhesives. This procedure is not recommended for preservation purposes as it irreversibly damages the enclosed item. The heat and pressure involved in the lamination process can damage documents, and the plastic can "off-gas", causing a chemical reaction with the enclosed materials. Additionally, the adhesives used in lamination are often acidic and can cause inks to bleed.
An alternative to lamination is encapsulation, which involves enclosing documents between two clear sheets of uncoated polyester without the use of adhesives. This method is more expensive and time-consuming but is suitable for fragile documents, photographs, certificates, and small textiles. Encapsulation should not be used for artefacts with friable media such as pencil, charcoal, or chalk, as the electrostatic charge can cause the media to transfer onto the plastic.
In terms of the plastic cover on paper, this is known as coated paper or coated cover stock, and in the printing industry, it is referred to as "C1S" (Coated, 1 Side). This process leaves a thicker, more rigid plastic coating on both sides of the paper. While lamination is not recommended for preservation, it can be useful for other purposes such as adding a decorative touch or protecting items from moisture. For example, some notebooks and decorative boxes have a thin film of transparent plastic coating the paper, which allows them to be easily cleaned with a damp cloth.
There are various products available for laminating paper, such as thermal laminating sheets and laminating machines. These products aim to provide clear, durable results and good adhesion. However, some customers have reported issues with thicker papers not adhering well to the laminating sheets.
