Construction

Various types of closed-end, multi-layer envelopes with an open mouth are used for specific applications in the construction and building industries. For cement packaging, non-laminated envelopes are commonly employed. These envelopes are designed to withstand the weight and abrasive nature of cement while providing adequate protection during handling and transportation.

On the other hand, for building materials that may require additional protection, laminated envelopes are utilized. The lamination adds an extra layer of durability and resistance to environmental factors such as moisture and dust, ensuring that the materials remain in optimal condition until they reach their final destination.

This distinction between laminated and non-laminated envelopes allows for tailored packaging solutions that meet the specific requirements of different types of products, enhancing both their protection and usability in the construction sector.
