What Are Core Product Characteristics of Exceed™ 1018 Series mPE?
Superior balanced toughness, supporting lightweight film cost reduction
This series boasts excellent tensile, impact, puncture, and tear resistance properties. Elmandorf longitudinal tear strength reaches 220g, and its transverse tear strength is as high as 370g. The longitudinal elongation at break is 500%, and the transverse elongation is up to 640%, exhibiting excellent tensile toughness. Under the same protection standards, it can achieve thinner film production while ensuring packaging resistance to tearing, puncture, and low-temperature impact.
Top-tier optical performance, suitable for high-end visual packaging
The uniform and regular molecular structure significantly reduces crystallization defects, resulting in finished films with low haze, high gloss, and clear transparency, free from appearance defects such as crystal points, watermarks, and streaks, and exhibiting excellent film surface flatness. It can be directly used in high-end transparent food packaging, boutique daily chemical packaging, and high-transparency agricultural films—scenarios with stringent requirements for appearance and texture.
Excellent low-temperature heat-sealing and anti-contamination sealing performance
This series features low-temperature initiation sealing, a wide heat-sealing window, high heat-sealing strength, and excellent heat-adhesion performance, making it suitable for high-speed filling and high-speed bag-making production lines. Even with small amounts of contaminants such as grease, powder, and sauces in the sealing area, a strong seal can still be formed, minimizing issues like leakage, bursting, and wrinkling. It is perfectly suited for automated packaging production of food, daily chemicals, and powder materials.
Highly versatile, with stable processing and high compatibility
This Exceed™ 1018 series of mLLDPEs exhibits excellent thermal stability, resisting degradation, leaching, and die carbon buildup during high-temperature processing, effectively reducing equipment cleaning frequency and improving production continuity. It is perfectly compatible with mainstream film processing technologies such as blown film, cast film, and multilayer co-extrusion. It can also be blended and modified with LDPE, ordinary LLDPE, and other materials in any proportion, flexibly adjusting film hardness, smoothness, and processing flowability to meet diverse production needs.
Full-dimensional compliance and safety
The Exceed™ 1018 series has passed stringent food contact safety certifications, is non-toxic and harmless, and does not leach harmful substances. It can be directly applied to various food packaging scenarios, including fresh produce, frozen foods, and baked goods. It also meets the compliance requirements of multiple fields, including civilian, industrial, and agricultural applications, combining versatility and safety.
