Use LDPE Bags for Efficient Packaging

November 17, 2016


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

ldpeLow 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.

What are LDPE bags?

Low Density Polyethylene bags or LDPE bags are often considered as a better replacement to ordinary plastic bags, which are thick and non-biodegradable. Ordinary plastic bags are a hazard to the environment as they cannot be easily disposed of. This is where Low Density Polyethylene bags become important as they have a high degree of transparency and flexibility. In comparison to the ordinary plastic bags, the LDPE bags are better suited to store perishable items like food products and medicines. These bags keep food products fresh and increase the shelf life of pharmaceuticals like tablets, bottled medicines etc. LDPE bags also offer protection against bad odour, mold, mildew and various other spoilage organisms.
Low Density Polyethylene bags are designed in such a manner that they are unaffected by moisture, dust, air and other impurities present in the outside environment. The bags are also odourless and toxin-resistant, thus making them a better choice over ordinary plastic bags. LDPE bags are available in a wide range of shapes and sizes and can also be custom-made depending on the specific requirement of the customers.

Why LDPE Bags are Better than Plastic Bags?

Nowadays, the general trend is of people preferring Low Density Polyethylene Bags rather than plastic bags. What are the reasons behind this change? Read on to know more…
The major advantage of ordinary plastic bags is that they are “ordinary”. They are very cheap and easily available. In spite of all these plus points, more and more customers are opting for LDPE bags. This is because of the following reasons:

ldpe bag superior than common bags1) The Low Density Polyethylene bags are thick gauged in comparison to the regular plastic bags and this work out well when heavy and a number of objects are to be carried. The ordinary plastic bags cannot carry this much weight and is one of their biggest disadvantages.

2) The second advantage of switching to LDPE bags from ordinary plastic bags is that they are highly recyclable and reusable. Most of the plastic bags available in the market are for only one-time use. That, however, is not the case with LDPE bags. These bags can be reused multiple times and come in handy as kitchen catchers. Low Density Polyethylene bags are known to have a reuse rate of around 40-60%.

3) People also choose Low Density Polyethylene bags over ordinary plastic ones as they do not biodegrade. This does not apply for bags with additives. As they are not biodegradable, these types of bags are highly useful for landfills.

4) Another major benefit of opting for LDPE bags is that it shows great resistance to high temperature. So even if the outside atmosphere is not conducive, products kept inside these bags will not be affected as it is highly adjustable to the surrounding environment.

5) The LDPE bags are also preferred for their leak-proof texture and their resistance to punctures. Ordinary plastic bags always buckle under excess weight.

Why are LDPE bags so popular?

Mostly known as the”Bags for Life”, Low Density Polyethylene Bags or LDPE Bags, are hugely popular among companies as well as the general public. At home, these bags are usually found in kitchens, where they are used to store food items. As these LDPE bags are recyclable, they can easily be reused as kitchen catchers. The Low Density Polyethylene Bags usually available in the market are very thick, heavy duty plastic ones. These bags witness high demand among customers because they are easily recyclable and therefore prove to be most beneficial for households. The majority of the LDPE bags being used in houses is known to have 30% recycled content.

Other Uses of LDPE

Most people are of the view that LDPE is only used to manufacture bags but that is not the case. Low Density Polyethylene is used to manufacture many other products. These include adhesives, plastic bags for packing purposes in dry cleaning, bakery, bin liners and frozen food. LDPE is also the source material of the coatings used in paper milk cartons and coffee cups.

Understanding the Recycling Process of LDPE bags

Additionally, LDPE is used to manufacture adjustable containers for food products like squeezable honey and jam. It can also be utilized to produce lids for ice-cream boxes, sealants, shrink wraps, toys and wire coverings.

Environmental Hazards of LDPE bags

Although Low Density Polyethylene Bags meet most of the requirements of the consumer, they also have negative effects. LDPE bags are not very environmentally friendly as their source material is a non-renewable one. Another drawback is that because of their weightless nature, they cannot be disposed of so easily. The excessive use of Low Density Polyethylene Bags is harmful to the environment as it is not biodegradable.

There Are Positives too

The first benefit is that LDPE bags are recyclable and can be converted into a wide variety of products. These include compost and garbage bins, film, plastic, different kinds of furniture, garbage can liners, paneling in homes and offices, plastic lumbers and shipping envelopes.

There are three types of LDPE bag recycling. There is curbside recycling where the LDPE bags/products are collected through the local curbside recycling operations. The second is Grocery store drop-off programs where certain local groceries, take in LDPE plastics for recycling purposes. Third and last are reusing the plastic at home to either store more food, office stationary and many other items.

The Invisible but Important Support: Plastic Multi Layer Bags

November 12, 2014


In today’s world, there is nothing more widely and frequently used product than polyethylene or multi layer bags popularly known as plastic bags. One cannot imagine life without plastic. It has become so embedded in our life that however environmental conscious we become, there is no way around using plastic.

Multi-layer bags or the plastic bags protect the contents from various environmental factors like rain and dust. Low-density polyethylene (LDPE) is most commonly used for making plastic bags. For waterproofing solutions also, multi layer bags are a very good choice. These are reliable and cost effective, and protect the contents by keeping them in the same condition as it was when packed. LDPE Bags are widely used in day today life and also in different industries like automobile, electronics, pharmaceuticals and garment for packing purposes. Available in various sizes, these bags can be customized as per the requirement.

Advantages

  • Reliable and cost effective
  • Water proof and dust proof
  • Flexible, yet strong
  • Chemical & corrosion resistant
  • They are translucent or opaque with lower tensile strength.
  • A preferred form of food grade packaging material for liquids like juice and milk

Manufactures today also employ the same method to make LDPE that was used in 1933 to manufacture low-density polyethylene (LDPE) as the first grade of polythene. This method involves using a high pressure process via free radical polymerization. These bags are translucent or opaque, quite flexible yet tough and with lower tensile strength and has high resilience.

Although, there are many competing products, the demand for multi layer bags is still very strong in today’s market.

Triple Laminated Bags

The food grade ability of LDPE bags has ended the search for a cheap reliable packaging solution for both dry and wet food products. The Multi Layer Bags are a preferred form of food grade packaging material for liquids like juice and milk. The cartons are made of liquid packaging board, which is a laminate of paperboard and LDPE as the waterproof inner and outer layer, and often with a layer of aluminum foil, thus making it an aseptic packaging.
