What are LDPE bags?
Nowadays many bags are available in the market, which are used for different purposes like storage, cold storage, taking items from one place to another among others. The most commonly used bags are triple laminated bags, multi-layer bags, pharma grade bags and one of the most important, LDPE bags (Low Density Polyethylene Bags).
Low Density Polyethylene Bags are of the most widely used bags, which are easily available in the market. So why is there so much demand for these type of bags? The answer lies in their unique properties. These bags are considered to be the most user-friendly among all the bags meant for storage. They are commonly known as “Bags-for-Life”. The LDPE bags are thick gauged and heavy duty and thus are able to carry heavy things.
LDPE bags are one of the most eco-friendly bags being sold in the market. They can be recycled very easily and thus do not prove to be a big hazard to the environment. They find use mainly in the everyday functioning of households and other businesses. Like all other products, LDPE bags also have their negative points. These bags are made from a non-renewable source and therefore are non-degradable. So their disposal can be a cause for concern sometimes.
Different types of Packaging Bags
Low Density Polyethylene bags can be divided into the following categories depending on their use. They include:
Linear LDPE bags: Linear Low Density Polyethylene bags are LDPE bags but with a thinner gauge. They have all the best and unique features of LDPE bags. They are mainly used as food bags, newspaper bags, shopping bags and garbage bags. In general, they find great use in the kitchen where they are kept as food storage in refrigerators and freezers.
Medium Density Polyethylene Bags: These types of bags are not known to be very strong and stretchy and there fore are not used while carrying or placing heavy products. This form of Polyethylene bag has two important uses –
1) as a garbage bag material and
2) in the packaging of various paper products like toilet paper and napkins. The main advantage of this type of Polyethylene bag is that it is more clearer than High Density Polyethylene bags.
Polypropylene Bags: Last but not the least, we talk about Polypropylene bags or PP bags. These bags are much in demand due to their high chemical resistance. The most important characteristic of PP bags is their high melting point and therefore, they are widely used for heat-sealing.
