Low-density polyethylene
Clear plastic bags on a roll are a cost-effective solution for storing products in bulk. They are made from virgin poly ethylene and are safe for contact with food. You can purchase more than one roll at a time to get a better shipping rate. You can also combine these bags with other types for greater savings. To learn more, read our policy on bags on a roll.
Low-density polyethylene (LDPE) is an excellent material for plastic bags. It is lightweight and durable and meets USDA and FDA specifications. It is also translucent, making it a great choice for shipping and storing food and other items. The LDPE resin is used in the making of many plastic products, including shopping bags, water bottles, and industrial parts.
Low-density polyethylene (LDPE) is produced through the process of ethylene polymerization, which produces long, linear chains of hydrocarbons. These plastics are available in various densities and are used for a variety of applications. LDPE is popular because of its low-density, high-tensile strength, and improved flexibility. Linear low-density polyethylene (LLDPE) has an enhanced flexibility and tensile strength, and is often used for packaging sensitive items.
Low-density polyethylene bags can be white or clear. These plastic bags are popular for consumer packaging, since they are flexible and stretchable. They have good moisture barrier and gas barrier properties. But they do have some drawbacks.
Acrylics
Acrylic is a transparent thermoplastic that is used in a variety of applications. It is highly durable and shatter-resistant. It can also be made fluorescent, UV-tolerant, anti-static, and abrasion-resistant. This versatile material is often used in sheet form. It is seventeen times more impact-resistant than glass, making it an ideal choice for many applications.
Acrylic sheets are available in dozens of standard colors. They are usually sold under Rohm & Haas color numbers. In addition to decorative uses, acrylics can be used for plastic histology and electron microscopy. They are also commonly used in tanning beds, where they protect the occupant from the UV rays.
Polyester resins
There are a variety of different types of polyester resins. These resins are made from a polyester solution that is mixed with a monomer. This monomer helps the polyester chain crosslink. Some types of polyester resins are better suited for certain applications, while others are better suited for general-purpose uses. They are characterized by their chemical resistance, good dimensional stability, and ease of processing.
Clear plastic bags are generally made from low-density polyethylene (LDPE) or polypropylene (PP) materials. LDPE has a higher tear-resistance and strength than high-density polyethylene. Low-density polyethylene also exhibits less branching, which results in a frosted appearance. Clear plastic bags should have minimal branching to ensure optimal clarity. Polypropylene bags, on the other hand, are inexpensive and available in many varieties. However, polypropylene bags are not as durable as polyethylene bags.
Polyester resins can be made from a variety of different compounds. Saturated dibasic acids, acrylics, and vinyl monomers are common examples. These resins have many uses in the chemical industry, including plastic bags, tubing, and lavatories. They are also useful for outdoor applications, including coil coating.
