What is a honeycomb paper sleeve? The original pulp kraft paper is connected by adhesive to form countless hollow three-dimensional hexagonal cell structures, forming an overall honeycomb load-bearing sleeve with very strong buffering capacity. Suitable for cylindrical items such as wine, cosmetics, ceramics, etc. As an innovative protective packaging that is 100% biodegradable and recyclable, it is the ideal alternative to plastic packaging used to protect fragile items such as glassware.
