A Transparent Choice with Both Strength and Toughness: High-Strength, Tear-Resistant Transparent PP Sheets, Suitable for Multiple Applications
In scenarios requiring both transparency and robust protection, ordinary transparent PP sheets are often limited by insufficient unidirectional strength and susceptibility to tearing. High-strength, tear-resistant transparent PP sheets, through special process optimization, possess excellent tensile and tear resistance on both sides. They allow for the display of internal items while resisting external impacts and tearing, making them the preferred material for food packaging, electronic protection, and daily necessities molding.
I. Core Advantages: Bidirectional Strength + High Transparency, Solving the Pain Points of Ordinary PP Sheets
The core competitiveness of this type of transparent PP sheet lies in its "balanced bidirectional strength." Unlike ordinary PP sheets (which often suffer from unidirectional tearing), it achieves consistent strength on both sides through raw material modification and process adjustments, while maintaining high transparency, perfectly balancing "visibility" and "protection."
1. High Strength in Both Directions, Resistant to Tear
Superior Tensile and Tear Resistance: By adding toughening agents and optimizing the extrusion process, the sheet's longitudinal and transverse tensile strengths are both ≥35MPa, and its elongation at break is ≥250%—making it difficult to tear from any direction, even with slight scratches from sharp objects, preventing further tearing (ordinary PP sheets often have a transverse tensile strength below 25MPa, making them prone to tearing laterally);
Smooth and Flawless Surface: After extrusion molding, the sheet undergoes high-precision calendering, resulting in a smooth and flat surface free of scratches, black spots, and other impurities, further enhancing its transparent display effect and making it suitable for high-end packaging scenarios with high aesthetic requirements.
3. Food-grade safety and weather resistance, suitable for multiple scenarios
Compliant food-grade: Made with food-grade PP resin and environmentally friendly additives, meeting food contact standards, free of bisphenol A (BPA), heavy metals, and other harmful substances, safe for direct contact with food (such as fruits, baked goods, and prepared meals) with no risk of migration;
Stable temperature resistance: Withstands a temperature range of -20℃ to 120℃, does not crack at low temperatures (suitable for refrigerated food packaging), and does not deform at medium to high temperatures (suitable for short-term hot-fill scenarios, such as hot soup and porridge packaging below 60℃). Maintains stable shape during room temperature storage and will not age or become brittle due to changes in ambient temperature.
