Depending on the business, plastic bags are used in a variety of ways. They are used for packaging products, transporting goods, and many other applications. These types of bags come in a variety of designs, sizes, and shapes. The most common types of poly bags include LDPE, HDPE, and polypropylene.
LDPE, also known as Low Density Polyethylene, is a form of polyethylene that has a lower density than HDPE. It is a transparent plastic that has good moisture barrier properties. It is also very flexible and easy to tear. LDPE is also an FDA-approved plastic. It is often used in food-safe bags and can be heat sealed.
HDPE, or High Density Polyethylene, is a semi-translucent, lightweight plastic that is also opaque. It is used for food-safe bags and is widely available at retail stores, grocery stores, and restaurants. It is also FDA-approved for food handling guidelines. It has high resistance to water and temperature changes. It is also a good choice for carrying heavier loads.
Polypropylene, also known as polypropylene film, is another common type of poly bag. It is lightweight, but is also suitable for containing fragrances and oils. It is used for packaging products because of its high tensile strength and superior heat resistance. It also maintains the highest clarity of all poly substrates.
Polypropylene is also a good choice for protective packaging because it is resistant to moisture and airborne contaminants. It is also very breathable. Polypropylene can be used for many types of applications, including packing food and products, as well as for medical uses. Its high clarity makes it a good choice for packaging materials that need to be viewed inside a container.
Polythene is another type of plastic. It is made from crude oil, and is used for packaging products. It is also commonly used in consumer packaging because it has good moisture barrier properties and is flexible. Nevertheless, it must be manufactured in accordance with Commission Directive 92/39/EEC and 95/3/EEC.
LDPE, or Low Density Polyethylene, is characterized by a low density and is commonly used for food-safe bags. It is also used for packaging lightweight items, such as food, electronics, and automotive parts. It is often used for heat-sealing and can be dyed to make it tinted. LDPE is also commonly used for single-use produce bags. It is also used for industrial packaging, especially for transporting products. It is also used for medical packaging because of its excellent chemical resistance.
LDPE is also used for general-use plastic bags. LDPE can be used for film wraps, but it is less durable than HDPE. It has good clarity and can be used to protect items from dust, airborne contaminants, and moisture. LDPE is also used for heat-sealing, but it is not 100% PCR LDPE resin.
Polythene film must be manufactured in accordance with Commission Directives 90/128/EEC and 95/3/EEC. It must also comply with EU food contact legislation in Great Britain and Europe. It must also meet Commission Directive 93/9/EEC and 95/3/EEC.
