Frequently Asked Questions (FAQ) on Coreless Stretch Film
Q1: What is the primary material of coreless stretch film?
A: Most premium products use Linear Low-Density Polyethylene (LLDPE), occasionally blended with MDPE or proprietary additives for extra tear resistance and clarity. Biodegradable or recycled content options are available.
Q2: Which technical standards are products tested to?
A: Products adhere to ISO 9001 (quality), ASTM D882 (tensile/elongation), and where applicable FDA 21 CFR for food contact. Consistency is validated via ISO 527 or ANSI/ASTM benchmarks.
Q3: What is the recommended roll thickness and size for automatic stretch wrappers?
A: For automatic machines, 17–23 microns, widths 500–1000 mm are common. For handwrap, 12–20 microns, any width under 500 mm is preferred.
Q4: How is the film roll’s stability ensured without a core?
A: Proprietary CNC winding guarantees uniform roll density. Special edge-forming and tension control systems avoid telescoping or collapse, surpassing traditional core stability for most applications.
Q5: Can coreless film be used in high-humidity or corrosion-prone environments?
A: Yes, films are hydrophobic and inert to most chemicals. Surface options are available for anti-static, UV, or anti-corrosion needs in petrochemical, marine, or municipal applications.
Q6: What certifications support product sustainability claims?
A: Leading products are ISO 14001-certified for environmental management, carry GRS (Global Recycled Standard) or comparable eco-labels, and may also meet EU REACH or FDA food-contact requirements.
Q7: How are installation and roll changes handled compared to core-based films?
A: Operators receive no-contact ends for quick swaps; auto-detect systems in fully automated lines ensure seamless feed. With lighter rolls and zero core waste, manual change time drops by 20–35%.
