As much as we love stepping out and breathing in the fresh air, fact remains that it is not just revitalizing oxygen in the air. It also contains specks of dust, spoilage bacteria, humidity and other unwarranted particles. While our bodies are trained to survive and thrive despite it all, the food and the products that we consume are unfortunately not. This is where polyethylene films come to our rescue. Let’s explore what a polyethylene packaging film is, along with its uses, types and many advantages-
What Is Polyethylene Film(PE film)?
To put it simply, a Polyethylene (PE) film is essentially a plastic film made from hydrocarbons, which is mainly obtained from natural gas or petroleum. Because of its wide use, polyethylene has many names in the market – ‘plastic sheeting’, ‘polyethylene sheet’, ‘poly sheeting’, or ‘poly film’.
It is a direct product of petroleum, which is why its costs are subject to the change in accordance with the oil prices. Usually, it is made available in rolls. Polyethylene sheeting is your best bet when it comes to plastic protection. The beauty of these flexible films lie in the fact that they can be tailored to perfectly fit into a project’s requirement. This is done with the help of additives such as U.V. inhibitors, fire retardants, and other anti-static additives. These additives are adept at changing the functionality of the film, ensuring that it best serves its purpose.
What is polyethylene film used for?
With its multiple features and unquestionable benefits, the list of polyethylene film uses is rather long. These films are then used in construction as vapor retarders, window films, flooring and countertop protection, and even in roofing. They can also be used to seal off rooms, cover building materials, and be used in lead abatement projects. It works wonders when it comes to slowing down run-off on hills, and keeping lead out of the ocean during shipbuilding projects.
What Are The Common Polyethylene Film Uses?
Apart from being the most sought-after plastic film, it is the most cost-effective labeling material out there. This is one of the primary reasons for the polyethylene film’s increasing demand. It is used for a wide range of applications, to name a few primary ones:
Manufacturing Plastic Products
Protecting Machinery / Equipment
Covering Surfaces In Indoor Painting
What Are The Polyethylene Film Types?
Polyethylene films come in enviable variations. It can also be manufactured in different colours or be transparent. In addition, plastic sheeting comes in a wide range of thicknesses. The thicker the virgin film, the stronger it is. The film gets thicker as the numbers of mils increase. The three most common types of polyethylene are:
1. Low-Density Polyethylene (LDPE)
This one is commonly used to manufacture plastic products like shopping bags. It is a highly flexible material with unique flow properties.
2. Linear Low-Density Polyethylene (LLDPE)
This one is more or less the same as LDPE. The only difference is that it can be altered by adjusting the formula constituents using less energy during production. This potential gives it a winning edge over LDPE.
3. High-Density Polyethylene (HDPE)
This type of plastic has a denser form, and the end-result is usually stiff plastic, thanks to its highly crystalline structure. It is commonly used to manufacture garbage bins, milk and laundry detergent holders, cutting boards, and the likes. The HDPE plastic does a great job of protecting the groundwater from toxic chemicals from oil drilling or from landfills.
7 Advantages of Using Polyethylene Film
Its many advantages are what makes a polyethylene film a preferred choice. The below listed advantages vouch for their dependability-
1. Assured Protection:
The first and foremost responsibility of a polyethylene film is to provide excellent protection. It is leakage-proof, and great for heat sealing; meaning that it can be wrapped around the product and secured with an airtight seal. PE is quite popular in the electronic industry as it provides excellent protection from moisture and tampering, keeping the electronic components safe.
2. Extremely Lightweight:
The best part about these films is their easy management in terms of transport and storage. They are incredibly lightweight, and require very little storage space. Its easy transportation contributes to reducing the carbon footprint significantly.
3. Superior Flexibility:
Low-Density Polyethylene (LDPE) is soft, puncture-resistant, highly transparent, and heat seal-able, making it the ideal choice for wrapping products, tubing, and packaging of auto parts. The slightly denser version of LDPE is used to manufacture packaging bags for sharper objects.
4. Impact Resistance:
Poly sheeting is highly suitable for boat construction and protecting large containers that sail the uncertain sea waters. Why? It is chemical and impact-resistant, low maintenance, and facilitates buoyancy.
5. Highly Adaptable:
Polyethylene can be tailored to suit different needs. It comes in different colors, clarities, and thicknesses. It can best display the products, as well as keep them sheltered, if required. This PE trait makes it easier to advertise a product.
6. Low-cost Solution:
High-Density Polyethylene (HDPE) is extremely easy to process, yet economical. It is an opaque packaging leveraged for your everyday products like shampoo bottle, lotion bottles or flower pots; products that also demand a certain degree of marketing appeal.
7. Excellent Rigidity:
Given that they have a solid structure and are moisture-resistant, they are used to manufacture water bottles (along with the bottle caps), vegetable oil bottles, and milk cartons. Of all the plastic offerings, PE wears the crown when it comes to excellent rigidity.
PE protective film material and use
PE, whose full name is Polyethylene, is the simplest polymer organic compound with the most widely used polymer materials in the world today. The PE protective film is made of a special polyethylene (PE) plastic film and classified into high-density polyethylene protective film, medium-density polyethylene, and low-density polyethylene according to the density.
The biggest advantage of PE protective film is that the protected product will not be contaminated during production, processing, transportation, storage and use, and it will be corroded and scratched to protect the original bright and glossy surface, thus improving product quality and market competitiveness. . The current PE protective film is mainly used in the following industries:
1, hardware industry: computer chassis, galvanized sheet stamping, aluminum, stainless steel, titanium plate, plastic plate, glass, solar panels and so on.
2. Optoelectronic industry: LCD liquid crystal display, backlight board, cold light film, membrane switch, mobile phone screen and so on.
3, the plastics industry: ABS, PP injection molding products, PVC sheet, acrylic board, instrumentation, plastic lenses, paint parts surface protection and so on.
4, the printing industry: PVC, PC board, aluminum, film printing nameplate surface protection and so on.
5. Wire and cable industry: The protection of axle-mounted copper wire, semi-finished products, finished products and rolled products can effectively prevent dust pollution, prevent oxidation and prevent dirt.
6, the electronics industry: In the production, the general use of PE protective film is used to protect the finished product and semi-finished products, the line is not prone to scratches and bumps.
7, mobile phone digital industry: mobile phone film, also known as mobile phone beauty film, mobile phone protective film, can be used to frame mobile phone body, the screen of a cold film.
Top Benefits of Stretch Film
Stretch wrapping is one of the most popular unitizing and pallet wrapping methods on the market today. It is a stretchable plastic film that can prevent products from being damaged in the shipment process due to improper handling, sudden movements, or environmental factors.
It might look like heavy-duty cling film, but the stretch film is actually one of the most versatile, efficient and cost-effective weapons in your packaging arsenal.Designed to adhere to itself without the use of glues or staples, stretch film has a high coefficient of friction. To put this in simpler terms, once it’s wrapped over itself under pressure, it effectively holds itself in place.
Generally, it is used to secure goods on a pallet for transportation or warehouse storage, stretch wrap film is pulled around the load and stretched into place. The plastic has a memory and wants to return to its original size, which creates an “elastic band effect” and holds to load tightly in place.This means that stretch film can quickly and easily be applied to loads of varying sizes and shapes. It also means that removal is similarly quick and easy - you simply cut down one side to release the tension and then remove it by hand.
It can be deployed in a wide range of applications across a vast range of industries, there almost isn’t a packaging operation that couldn’t be improved by the intelligent application of stretch film.

Advantages and Disadvantages of Blister Packs
A forming film and lidding material are needed to create a blister pack that can be used for several purposes. It is usually the PVC plastic that is used to create the forming film and PVC Blister packaging has a lot of advantages over bottles and another type of packaging. Mostly plastic is used as a lidding material but either a printed or plain foil is mainly used in pharmaceutical products for safety purposes.
Blister packaging vs. Bottles
Studies show that more than 75% of the medicines in Europe are packed in blisters. While this percentage in the US may not be as high as 75%, it surely is a lot more than bottles. Besides, both consumers and producers have started to understand the benefits of blistering packaging. Bottles could be broken, and the patients don’t even know how many pills they have taken if they are using bottles.
Let’s take a look at the advantages and disadvantages of Blister packaging in detail.
Advantages of Blister Packaging
The first and foremost use of this sort of packaging is that it helps the patients follow the drug regimens. Drugs and medicine tend to have a longer life and more extended expiry date when this type of packaging is used. Another great benefit of this packaging is that there is a separate blister for each pill or capsule; the possibility of pills getting contaminated as a whole is entirely ruled out.
In this type of packaging, days of the week are incorporated on the sheet, so the patients have a better idea as to how often they are required to take their medication. Since aluminum sheets are used in the blister packaging, no type of contamination is possible but this has some costs too.
Despite the fact that it has a lot of advantages, there are also some disadvantages that cannot be eliminated. First off is that since aluminum is used for the entire package, the whole process takes a lot more time as compared to the time taken with plastic. Another rare disadvantage of this type of packaging is that it uses foil backing, and patients can push the medicines through the foil, but it is child-resistant. Finally, the sealing process to attach the plastic takes too much time, and if the proper equipment is not used, it could result in an increase in the cost too.
If we compare the advantages and disadvantages of this type of packaging, we will come to know that benefits outweigh the disadvantages. Everything comes at a cost, and there are no harmful effects or disadvantages that would prevent you from using it. However, a number of advantages of blister packaging make it a better option than the other types of packaging. Moreover, the fact that it also cuts the production cost is high for pharmaceutical companies that need to manufacture drugs and medicines in vast quantities. This is the reason this type of packaging is getting popular not only in the United States but all over the world.
