AI Technical Summary

Technical Problem

The challenge lies in finding a method to close mesh bags using sustainable materials like cellulose or recycled plastics without compromising productivity, mechanical properties, and without requiring a redesign of existing automated production processes, while ensuring the closure does not lead to accidental opening during storage, transportation, or handling.

Method used

A roll-up band with a coating pattern of thermally activatable adhesive material, specifically designed with main transverse and optional longitudinal stripes, is used to sandwich and join tubular mesh portions, ensuring effective closure without altering production rates or damaging the materials, even when made from non-thermoplastic or biodegradable materials.

Benefits of technology

The solution maintains production efficiency and ensures robust, tear-resistant closures for mesh bags made from sustainable materials, compatible with existing machinery and processes, without premature bonding or material degradation.

Abstract

A reel-sized band (1) having areas coated with a thermally activated adhesive material (2) following a coating pattern (3) that is repeated along the band with at least two main transverse strips (5a, 5b) extending between two longitudinal edges (1c) of the band and including areas (21) coated with a basis weight of thermally activated adhesive material between 35 and 130 g / m². A specific use of the band (1) is the making of mesh bags (10) and in particular for closing a portion of a tubular mesh (11) by interleaving said portion of mesh between two portions of the same or of two bands (1, 1') in conscientious order and with respective main transverse strips (5a, 5a') of the coating pattern (3) facing the mesh; the application of pressure; and the supply of heat.
