Packaging techniques refer to the methods used to enclose and protect products for distribution, storage, and sale. These techniques can include the use of materials such as cardboard, plastic, and glass, which are chosen based on the product's needs. Effective packaging not only safeguards items from damage but also helps in branding and attracting customers. Different packaging techniques can also enhance product visibility and usability. For example, vacuum sealing removes air to prolong shelf life, while blister packaging provides a clear view of the product. Additionally, eco-friendly packaging options are becoming popular as consumers seek sustainable choices.
