Paper cores designed for agricultural mulch film are highly practical and specifically tailored to the packaging requirements of these products. Mulch films typically come in large rolls that are wide and heavy, placing high demands on the paper core regarding compressive strength, toughness, and dimensional compatibility.
Cores used for this purpose are typically large-scale tubes with a wall thickness of 3.5–5 mm and an inner diameter exceeding 152 mm. Manufactured from high-strength kraft paper, they offer robust load-bearing capacity and compressive strength, capable of supporting the weight of the film while preventing deformation or damage during transport and storage. Furthermore, the length of the core can be flexibly adjusted to match the width of the film, ensuring the roll is fully supported and protected against external impurities and moisture, thereby preventing degradation or damage.
Additionally, these paper cores are made from eco-friendly, biodegradable materials that do not pollute the soil, aligning with the goals of green agricultural development and making them widely used in the storage and transport of mulch film.
