PE film wrapping is a plastic material widely used in the packaging and product protection industries. With many diverse applications and utilities, PE wrapping film is becoming one of the indispensable products in modern life. However, like any other material, PE wrapping film also has its advantages. advantages and disadvantages should be considered before use. Here are the advantages and disadvantages of PE film that users need to know.
With competitive price and timely delivery, Firsta sincerely hope to be your supplier and partner.
PE film, also known as PE wrap, is a thin elastic-plastic material used to wrap around products, boxes, crates, and pallets. It should be noted that the higher the elastic recovery rate, the better the membrane. The primary purpose of PE film is to stack products onto pallets and hold them correctly and securely during transit.
PE film is one of the widely used and available products, becoming the first choice of many users in recent years to pack all kinds of products, goods, and items. , protect components and machines from dust and agents that affect product quality.
PE film wrap is also used in many different industries such as shipbuilding, construction, agriculture, medical, …
Although PE (Polyethylene) film has many advantages, there are also some disadvantages as follows:
High-Density Polyethylene (HDPE) and Polyethylene Terephthalate (PET) are two types of commonly used plastics made for everyday use – from packaging to food storage, and containers for pharmaceutical products.
However, if one type of plastic is good for these purposes, why are both types commonly used?
This article will attempt to explain and outline the difference between HDPE and PET, their specific uses and why both products are required in equal measure.
Polyethylene Terephthalate (PET) is a thermoplastic polymer belonging to the polyester family. Thermoplastics liquidize at high temperatures and harden on cooling which creates a more rigid plastic material with a higher tensile strength.
PET is commonly used in the production of plastic bottles, food containers and packaging films. It’s also used in the pharmaceutical industry for medicine bottles, pill packaging, vials, inhalers and diagnostic test kits.
PET plastic is a must-have for any business dealing with the storage and transportation of delicate products. In the pharmaceutical industry, that need is larger than ever. Origin offers affordable, high-quality PET Bottles that can be used for a wide range of pharmaceutical products.

High-Density Polyethylene (HDPE) is another highly versatile thermoplastic known for its versatility for packaging and its protective qualities. HDPE is made using petroleum and formed through the process of polymerization.
It is commonly used in plastic packaging and protective materials — like plastic bottles and pipes. However, it’s also commonly used within the pharmaceuticals industry for packaging, medicine bottles, caps and closures, labware, pill bottles, prescription packaging and inhaler components.
HDPE has a high-density, linear structure that results in a rigid and tough material. However, Low-Density Polyethylene (LDPE) retains much of the tensile strength of its high-density counterpart – but is much less rigid in design. LDPE is commonly used for a more flexible form of protection like plastic bags or pharmaceutical IV bags.
The Main Physical Properties of HDPE Include:
HDPE plastic is essential for any business looking for a dense and rigid packaging material with a high tensile strength. Origin offers a range of HDPE bottles at a competitive price. These HDPE bottles can be used for storing delicate medicines – providing strong barrier protection against sunlight, moisture and heat.

HDPE and PET offer similar sustainability and recycling benefits. Both products are highly recyclable and can even be repurposed to create new products out of recycled materials.
Recycling HDPE and PET reduces the demand for virgin plastic, conserves resources and reduces landfill waste.
Additionally, the recycling process for HDPE and PET has a lower energy consumption than many other forms of plastic recycling or virgin plastic production.
Because both plastics can be recycled and repurposed in a way that benefits the environment and a business’s bottom line, many of them are choosing these materials as they promote a more responsible and sustainable approach to plastic production.
Both types of plastic are highly versatile and find use across many industries because of their protective properties.
Beyond the pharmaceutical industry, HDPE is commonly used to manufacture bottles and containers, pipes and fittings, construction materials and automotive parts.
PET is commonly used in beverage bottles, food packaging (as it’s considered food-safe by the FSA), textiles, personal care products and electrical insulation.
Both PET and HDPE have their uses in pharmaceutical packaging. PET is transparent, non-permeable, and chemical resistant. This makes it more suitable for liquid medications and volatile or harsh chemicals.
HDPE on the other hand, is much more durable, more impact resistant and does not corrode when storing most common pharmaceutical liquids.
The choice between PET and HDPE plastics will ultimately depend on what products you’re trying to package. For example, formulas in glass pipette bottles may need a more durable HDPE secondary packaging to protect the delicate glass from impacts, whereas other products, like pill trays, don’t require that level of durability.
HDPE is known for its impermeability — making it suitable for everything from packaging and containers, to pipes and outdoor furniture that are constantly exposed to the elements.
PET’s water-resistant properties mean that it can be used in the manufacture of water bottles, food containers and other liquid storage applications.
The melting point of HDPE (High-Density Polyethylene) typically ranges from 120 – 180°C (248 – 356°F) depending on the specific grade of HDPE and its chemical composition. PET (Polyethylene Terephthalate) has a higher melting point, ranging from 240 – 260°C (464 – 500°F).
HDPE is considered a relatively inexpensive plastic when compared to other plastics of similar composition and usage types. PET plastic is also available at a more modest price range, with HDPE being slightly more cost-effective on average. However, when compared to other plastics, HDPE and PET are both considered highly cost-effective.
HDPE and PET are two distinct types of plastic with unique chemical compositions and physical properties – this means that they’re not compatible to be mixed together. Attempting to mix HDPE and PET would result in a structurally unstable, incompatible blend. It’s possible to separate HDPE and PET plastics used in the same product to improve recycling, but it requires the use of two separate recycling methods upon disposal — making the finished product difficult to recycle.
Both HDPE and PET have good strength properties – although the specific strength characteristics differ. HDPE is known for its higher tensile strength and impact resistance. This makes it better suited for containers and products that are likely to undergo sudden impacts.
PET is still strong but not as rigid. Because of this, it’s more flexible and can be more easily moulded into bespoke shapes to achieve a unique design — something that’s difficult to do with rigid HDPE plastic.
