Paper core products come in many varieties, and their different characteristics determine their different uses. Their main uses in daily life are as follows:
1, High-grade seamless paper cores: seamless surface, extremely smooth, dust-free, environmentally friendly, cost-effective and easy for secondary processing; especially suitable for the high-speed winding of various ultra-thin plastic films, metal foils, paper, EVA film and other materials.
2, High-strength, high-smoothness paper cores: seamless surface, no waviness, high gloss, high strength, high straightness, high roundness, high surface hardness, moisture-proof and dust-free; suitable for the high-speed winding of various high-grade plastic films, metal foils and other thin materials.
3, Large-diameter paper cores: robust, suitable for stainless steel, color steel sheet, aluminum foil, copper strip, paperboard, construction and other industries; featuring heavy load capacity, low cost, energy saving and environmental friendliness.
4, High-strength cores: high compression strength and stable surface gaps, widely used in papermaking, film and other heavy-load, high-speed winding industries, with excellent cost performance.
5, Heavy-wall cores: wall thickness up to 25.4mm, and up to 75mm for special requirements, meeting special applications such as electronic glass fiber cloth, non-woven fabric, construction and decoration.
