50uM Red Low Density Polyethylene Film Moisture Resistant For Packaging

50 μm red low density polyethylene film, for packaging, agriculture, construction, medical, etc.


Low-density polyethylene (LDPE) film is a type of plastic film that is flexible, durable, and moisture-resistant.

It is commonly used in a variety of applications such as:


1. Packaging:

LDPE film is used in flexible packaging applications such as bags, shrink wrap, and stretch film.


2. Agriculture:

LDPE film is used in agriculture applications such as greenhouse covers, mulch film, and silage bags.


3. Construction:

LDPE film is used as a barrier protection material for construction sites, as well as for insulation and roofing.


4. Medical:

LDPE film is used in medical applications such as disposable gloves and medical packaging.


The main difference between low-density polyethylene film and high-density polyethylene (HDPE) film:

The difference is in their density and properties.

LDPE film has a lower density than HDPE film, which makes it softer, more flexible, and more transparent.

HDPE film, on the other hand, has a higher density which makes it more rigid, less flexible, and more opaque.

HDPE film also has a higher tensile strength and is more resistant to punctures, while LDPE film is more

conformable and easier to heat seal.

Overall, LDPE film is a versatile and cost-effective material for a variety of applications where flexibility and

moisture-resistance are important, while HDPE film is generally used in applications where strength and rigidity are more important.

50-micron opaque red LDPE (Low-Density Polyethylene) film has unique properties that make it suitable for various applications in

different industries. Below are some of the major application scenarios for 50-micron opaque red LDPE film:


1. Stationery Products:

50-micron opaque red LDPE is often used in the production of stationery products such as bookbinding covers, folders,

and packaging envelopes due to its water-resistant properties and vibrant red color.


2. Food Packaging:

The film can be used in the food industry for packaging various food items and snacks due to its opaque nature,

which provides an attractive packaging solution while protecting the contents from moisture, dust, and other contaminants.


3. Medical and Pharmaceutical Industry:

Opaque red LDPE film can be used for packaging medical devices, medicines, and other medical products due to its ability

to protect the contents from moisture, dust and other environmental factors.


4. Personal Care Products:

The film can be used for packaging personal care products such as shampoo bottles, razors, and soaps due to its excellent

barrier properties.


5. Packaging of Chemical Products:

The film is ideal for the packaging of chemical and hazardous products as it provides an excellent barrier to protect the products

from environmental factors.


6. Industrial Packaging:

50-micron opaque red LDPE film can be used in industrial packaging applications, particularly packaging of industrial components,

due to its strength, durability, and resistance to tearing.


To increase the mechanical properties and enlarge the application range for LDPE film,

several approaches can be taken. Here are some of them:


1. Blending:

Blending LDPE with other polymers can improve its mechanical properties and widen its application range.

For example, blending LDPE with linear low-density polyethylene (LLDPE) can improve its tensile strength, impact resistance,

and puncture resistance. Blending LDPE with high-density polyethylene (HDPE) can improve its stiffness and resistance to stress cracking.


2. Adding additives:

Adding various additives can modify the properties of LDPE film and enhance its mechanical properties.

Additives such as fillers, elastomers, and reinforcing agents can improve the strength, durability, and flexibility of LDPE film

and widen its application range.


3. Coating:

Applying a coating to LDPE film can improve its mechanical properties and enlarge its application range.

Coatings such as acrylic, urethane, and silicone can enhance the film's barrier properties, improve its adhesion and enhance

its printing quality.


4. Orienting:

Orienting LDPE film can improve its mechanical properties and widen its application range. Orientation involves stretching the film

in either the machine direction (MD) or transverse direction (TD) to align the polymer chains and improve its strength, toughness,

and tear resistance.


5. Cross-linking:

Cross-linking can improve the mechanical properties of LDPE film and make it suitable for high-temperature applications.

Cross-linking involves modifying the polymer chains of LDPE to form a three-dimensional network that improves the film's

thermal stability, chemical resistance, and stiffness.


6. Controlling Processing Conditions:

Controlling the processing temperature, pressure, and extrusion speed during LDPE film production can improve its mechanical

properties. Optimal processing conditions can ensure consistent properties of LDPE film and enlarge its application range.


In summary, blending, adding additives, coating, orienting, cross-linking, and controlling processing conditions are all methods that can be used to increase the mechanical properties and enlarge the application range for LDPE film.
