Lotrene Q2018N LLDPE for Blown Film

Lotrene Q2018N is a butene-based linear low-density polyethylene (LLDPE) resin developed primarily for blown film extrusion. It is commonly considered for flexible packaging applications such as shopping bags, food packaging films, freezer bags, and multilayer structures.

With a typical density of 0.918 g/cm³ and a melt flow rate of 2.0 g/10 min, this grade provides key reference values for evaluating material selection and extrusion requirements. Its 1-butene (C4) comonomer composition is characteristic of this LLDPE grade.

Q2018N contains no added slip or antiblock agents, allowing manufacturers to customize additive formulations according to the required film friction, blocking resistance, and converting performance.

Main Uses of Lotrene Q2018N

(1) Food Packaging Films

Potential applications include bread bags, food packaging bags, and other flexible packaging products. For direct food-contact applications, manufacturers should verify regulatory compliance for the specific grade, formulation, and intended market.

(2) Shopping Bags and Retail Packaging

Lotrene Q2018N is suitable for evaluating shopping bags, carrier bags, and general-purpose retail packaging. When developing the film formulation, manufacturers should consider film thickness, load-bearing capacity, and tear resistance to meet the requirements of different bag designs.

(3) Multilayer and Laminated Packaging Films

In multilayer packaging, manufacturers can consider Q2018N as one of the polyethylene components. Each layer serves a specific purpose, so resin selection should balance toughness, flexibility, and compatibility with the other materials to achieve the desired overall performance.

(4) Freezer Bags and Frozen Food Packaging

LLDPE Q2018N can also be considered for flexible films used in frozen food packaging. Since these products must withstand low temperatures and handling during storage and transportation, manufacturers should evaluate low-temperature toughness, puncture resistance, and seal integrity under actual operating conditions.

Purchasing Considerations for LLDPE Q2018N

Before purchasing or replacing an Lotrene LLDPE film resin, manufacturers should evaluate the following factors:

1. Processing equipment: Confirm whether the production line uses blown film, cast film, or multilayer coextrusion, and select a grade compatible with the process.

2. Melt flow rate: Determine whether the typical MFI of 2.0 g/10 min meets the requirements of the target film thickness, extrusion output, and equipment configuration.

3. Mechanical performance: Define the required tensile strength, elongation, tear resistance, and puncture resistance according to the packaging application.

4. Surface properties: Assess whether the film requires slip agents, antiblock agents, or other additives to achieve the desired handling and opening characteristics.

5. End-use requirements: For food-contact and other regulated applications, verify the relevant compliance documentation rather than relying solely on the product name or general resin properties.

6. Technical documentation: Request the latest technical data sheet (TDS), safety data sheet (SDS), and applicable compliance declarations. Confirm the exact grade, production origin, and batch information before placing an order.

Storage and Handling

LLDPE Q2018N should be stored and handled in accordance with the supplier’s technical documentation and safety data sheet. A clean, dry, and well-ventilated indoor storage area is generally recommended. Protect the resin from moisture, rain, direct sunlight, and excessive heat.

During extrusion, follow equipment operating procedures and maintain appropriate ventilation. Avoid contact with hot polymer and implement suitable measures to control dust and other workplace hazards.

For food packaging applications, confirm the grade’s regulatory status, applicable migration requirements, and additive restrictions in the target market before commercial use.
