What is LDPE 150E Resin

In the flexible packaging industry, low-density polyethylene (LDPE) is one of the most common base resins. However, in food contact applications, materials that meet the requirements of both mechanical strength and transparency as well as molding adaptability are rare. The LDPE 150E Resin launched by Dow is precisely an ldpe resin tailored for high-standard fields such as food packaging and industrial protective films.

01 | Material Positioning: Not only LDPE Resin, but also a comprehensive solution at the film level

As a food contact grade LDPE resin specifically designed for extrusion and blow molding processes, LDPE 150E has undergone multiple directional optimizations in terms of performance:

Flexibility and strength in balance: Vertical elongation rate up to 530%, preventing the film from being fragile or cracking.

Outstanding tear resistance: The maximum tear strength of Elmendov reaches 480g, meeting the challenges of packaging and transportation.

Food contact safety level: Complies with FDA and relevant food contact regulations, suitable for packaging of fresh, frozen and dry goods.

Uniform and stable film thickness: The melt index is only 0.25g /10min, which helps to keep the film material flat and consistent in size.

High impact absorption capacity: The drop hammer impact value is 430g, providing external force protection for the packaging process.

Meanwhile, this material has a good processing window, is compatible with general extrusion and blown film equipment, and does not require additional adjustments to the molding parameters.

02 | Typical Application: How does LDPE 150E solve the Pain Points of Multiple Films?

In the development of traditional thin films, the following problems are often faced:

  ・It has good film-forming property but low strength and is prone to damage during the packaging process.

  ・The mechanical properties are acceptable but not tear-resistant, which affects the user experience.

  ・The material is flexible but has unstable shrinkage and warps and deforms after printing or heat sealing.

And LDPE 150E resin precisely demonstrates unique advantages in these key links. For instance, in the production of fresh meat preservation film, this material not only meets the requirements for transparency and sealing, but also maintains stable performance in high-humidity environments, extending the shelf life and enhancing brand reliability.

03 | Who is suitable for choosing LDPE 150E resin?

If your products involve the following types, it is advisable to give priority to evaluating LDPE 150E:

Food packaging film manufacturer: It must comply with food safety standards and have reliable physical properties;

Industrial film manufacturing enterprises: There are strict requirements for tear resistance, impact resistance and thickness uniformity.

Export-oriented flexible packaging company: Pay attention to compliance with ROHS, FDA and other regulations as well as customer factory audit requirements;

Design units requiring thin-walled and soft film materials: such as films for automatic packaging lines, degradable composite film layers, etc.

06 | Processing and film blowing Suggestions: Master the key points for more efficient film output

Although LDPE 150E is easy to process, if one hopes to further improve the consistency and performance of the finished product, it is recommended to conduct reasonable control on the following parameters:

Drying treatment: Although LDPE has low hygroscopicity, it is recommended to maintain the temperature of the hopper at room temperature to 50°C to avoid excessive condensation of water vapor.

Melting temperature: Controlled at 160-190°C, and can be slightly adjusted according to the thickness of the blown film.

Suggested blow-up ratio: 2.5:1 to 3:1 helps with uniform stretching and enhances the transparency of the film.

Cooling system optimization: Adequate air cooling ensures stable film formation, which is particularly crucial in high-speed equipment.
Winding tension control: Avoid film wrinkles or uneven stretching, and improve the efficiency of subsequent printing and lamination.

07 | Frequently Asked Questions: Issues You May be concerned about when using LDPE 150E

Q1: Does LDPE 150E support composite film processing?
A1: Supported. Its surface tension is suitable for coating or corona treatment and can be used for compounding with multi-layer structures such as PA, PET, and EVOH.

Q2: Can it be used for frozen packaging?
A2: OK. It has good low-temperature flexibility and is particularly suitable for storage environments below -20°C, such as packaging of frozen foods.

Q3: How is the transparency of this material?
A3: LDPE 150E has excellent optical performance and is suitable for application scenarios where there are requirements for perspective effects.

Q4: How can I determine if it is suitable for my current device?
A4: This material is compatible with standard single-screw blown film machines and double-layer/triple-layer co-extrusion equipment. If there are already basic LDPE products, they can basically be seamlessly connected.
