LDPE Bags

LDPE bags, also known as LDPE plastic bags, are really useful and necessary in modern packaging. Low-Density Polyethylene (LDPE, Resin Code #4) is a thermoplastic that controls the world of flexible packaging because of its softness, outstanding clarity, and excellent stretch as opposed to other plastics. In contrast to HDPE, which is stiffer and more solid, LDPE offers excellent flexibility, which is why it is best used in applications where it is necessary to have excellent puncture resistance and product visibility. Continue reading to know all about LDPE polythene bags.

What are LDPE bags made of? LDPE bags are formed by polymerizing ethylene gas and their structure is of considerably low density, highly branched. They are thermoplastics, and thus they become soft at high temperatures and hard at cold temperatures. It is the special structure of the polymer chains within the bags of LDPE that provides the bags with an unprecedented level of clarity, softness, and elasticity, to the extent of being brittle plastics such as polystyrene or even tougher HDPE. What are LDPE bags features?

• High clarity and transparency, which present contents in a glamorous way.
• Excellent flex and stretch that will not crack even when loaded.
• The LDPE is safe because it is used in the food, industrial, and pharmaceutical industries due to its moisture and chemical resistance.
• Thickness is typically 12 to 200 microns, and the lighter ones are used in retail or food, whereas the heavier ones are used in industrial or waste.

What are LDPE bags for plastic forms? Here are some LDPE plastic examples:

What are LDPE bags used for? They have a moisture-barrier performance, are economical, and durable; this makes them important for different industries. What are LDPE bags used for in food and other uses?

• LDPE bags for food packaging

Food packaging bags made of LDPE are approved by the FDA, are non-toxic, and BPA-free, which allows them to be in direct contact with fresh products, frozen products, meat, and bulk dry goods. They contain moisture and contamination and are better than PVC, as they are inert and conform to international regulations.

• LDPE bags for pharmaceutical use

LDPE Pharmaceutical use bags offer contamination-free handling, and sterile medicine packages and pill pouches, covers of medical devices. Very high standards of cleanliness and quality are fulfilled, and they are incompatible with sterilization procedures, such as autoclave and gamma irradiation.

• Construction and Industrial Case Studies

What are LDPE bags used for in construction? Sand, aggregates, insulation, and cement are contained safely, and goods are not exposed to any moisture, dust, or abrasion of the worksite. Excellent tear and puncture resistance guarantees a good performance in harsh work site environments.

• Retail and Consumer Application

LDPE shopping bags can provide a long lasting, lightweight and printable solution to retailers. LDPE zip bags support everyday household storage and consumer products with simple resealing and high versatility.

LDPE bags manufacturers are subjected to a standard process which entails extrusion of LDPE resin into LDPE films, blowing, sealing and cutting to size with optional printing. Quality depends on the type of resin used; virgin resin provides more clarity, strength, and compliance compared to recycled LDPE, with good quality recycled LDPE.

Personalization is accepted as standard, and the thickness (12-200 microns), colour, size, branding, and performance additives (UV inhibitors, anti-slip textures) can be customised to meet application or marketing requirements of LDPE bags suppliers.

Are LDPE bags recyclable? Yes. LDPE with Resin Code 4 is collected at numerous drop-off or store collections, but most curbside recycling programs do not accept it because of contamination risks and sorting issues. New bags, film, and plastic lumber are made using recycled LDPE, which helps in closed-loop, sustainable cycles of materials.

Here are some advantages of using LDPE bags:

• LDPE bags are lightweight and can be transported easily.​
• They are powerful and can stretch and bend without tearing so easily and hence can support heavy things to be carried without breaking.​
• These bags are great in preventing moisture and water, food and other products that are likely to be spoilt or damaged.​
• LDPE has the ability to resist a variety of chemicals and therefore, the bags can hold products that may leak or be in contact with cleaning agents.​
• They are also cheap to manufacture and purchase and therefore easy to buy by businesses and consumers.​
• LDPE bags are recyclable and in some cases they are produced with special materials so that they can be easily degraded after use.​
• The bags are transparent, so you can easily look inside and this is beneficial in the stores and kitchen.​
• They also make it easy to print labels or the company logos on the bags directly to brand the bag easily.​

The global trade LDPE bags HS code is usually 3923.21, which includes items such as: Articles to convey or pack goods of plastics; Of polymer of ethylene. This code simplifies the processes of customs, tariffs, as well as international supply chain logistics between LDPE bag exporters and importers.

Iran is a key regional exporter of LDPE grades of films that are used to make shopping bags, dairy films, etc. The top manufacturers are large complexes of petrochemicals as BIPC, Amirkabir, Laleh, and Mahabad. Typical Iranian grades 0218, 0208, 2420H, 0075, can be used in a wide range of applications, including retail bags, lightweight, mediumweight, and heavyweight industrial wrappings. Shobeir Shimi is one of the most trustworthy and experienced suppliers of these materials.
