When it comes to flexible packaging films, there are many options to choose from. But there is one film that is often a top pick because of its versatility and high-performance characteristics &#; PET packaging film.
You will get efficient and thoughtful service from Firsta.
PET stands for Polyethylene Terephthalate. It&#;s often referred to by its common name, Polyester, but in the flexible packaging world it&#;s better known as PET.
PET is a thermoplastic-engineered film, which means it can be formed and manipulated in different ways when a specific heat source is applied to it. It&#;s also one of the most environmentally friendly thermoplastics on the market.
Polyester film has been around for decades. It was invented in the s by the U.S. fiber manufacturer, DuPont, under the Dacron® name. Over the next several years, the use of cellophane in various applications soon dwindled as clear polyester film gained popularity because of its strength, insulating properties, and resistance to chemicals and heat. Within two decades of its creation, the film was an industry leader &#; and still is.
So how did PET film become one of the best multi-use plastic films around? Compared to other common films in this category, it delivers a lot more benefits because of these polyester film properties:
There are several types of PET film that meet a wide range of packaging applications.
There are also many grades of PET film that make it compliant with FDA and USDA regulations. Common applications that might require FDA or USDA compliance would include packaging for the food and beverage industry and the medical/healthcare field where sterilized packaging is needed for products such as face shields or surgical instruments and other medical devices.
At PennPac, we carry extensive product inventory including plain, treated, heat-sealable, metallized, and coated polyester films &#; available in different thicknesses, widths, and properties, and in both rolls and sheets.
Our films include:

High-density polyethylene, also known as HDPE, is another common packaging solution used in the food and beverage industry among other industries. Like PET, it&#;s lightweight and impact resistant but there are a few key differences between the two.
So which packaging option is best? It all comes down to your application needs. PET is likely the better choice for food and beverage packaging, with HDPE being the better option for heavier-duty packaging and shipping needs.
As mentioned earlier, the food and beverage industry is a big user of PET film because of its food-safe qualities. But many other industries rely on PET film. Here are just a few examples:

PET protective film-Industry knowledge
PET protective film is made of polyethylene terephthalate (PET) material, which has the advantages of high transparency, good weather resistance, scratch resistance and wear resistance.
1. PET material characteristics:
(1) Transparency: colorless and transparent or slightly yellowish and transparent; the surface is smooth and shiny. The hardness is 1.5-2.0g/cm3, which is much higher than that of glass; the tensile strength is 70-150MPa.
(2) Heat resistance: It can be used for a long time at a high temperature of 120 degrees without deformation and melting; it can withstand short-term use at 180-220 degrees, and it can be used for a short time at a temperature of 240 degrees.
(3) Moisture-proof: It has good air permeability and water permeability, the water absorption rate is only 0.03-0.04%, and after absorbing water, it can easily dry and form a film without adhering to dust and other dirt.
2. Application of PET protective film:
It is used on the protective layer of electronic products such as mobile screens, computer display screens, LCD TV screens, digital camera display screens, etc. to play a waterproof and dustproof role. Due to its excellent characteristics, it also has a wide range of applications in the industrial field, such as automobile dashboard covers, etc.!
3. Purpose of pet protective film:
(1) Suitable for decoration and protection on the surface of various electronic products:
For example, the protective covers of mobile cases and laptop screen films can all use pet protective films! Of course, various electrical products in our daily life can also use it to prevent dust from entering the inside of our equipment! For example, the outer hood cover of the air conditioner can be protected by it! In addition, things like refrigerator crispers can also be used! (However, it should be noted that these items must be covered with special plastic films to provide good protection!).
(2) Application in industrial fields:
For example, the shells of some large machines or the panels of mechanical equipment can be protected with PET protective films! (But be sure to choose the right material!) In addition, some large mechanical parts or metal parts can also be used. (Be careful to choose the appropriate material!) In addition, some parts on large mechanical equipment can also be protected with PET protective film (be careful to choose the appropriate material)!
(4) Others:
In addition to the ones mentioned above, there are some other uses for which PET protective film can be used. For example, the plastic bottles we often use in our daily lives can be made of PT material (of course) Only use the special plastic wrapping paper). And it can also be used on some more sophisticated equipment.
