Form-fill-seal machines are automated packaging systems that create packages by forming, filling, and sealing them in one continuous process. These machines are commonly used in the food, pharmaceutical, and consumer goods industries to efficiently package products. Primary packaging refers to the immediate packaging that comes into direct contact with the product, such as pouches, bags, or sachets. Form-fill-seal machines are used to create primary packaging by forming the material into the desired shape, filling it with the product, and sealing it to protect the contents. Secondary packaging, on the other hand, refers to the outer packaging that holds the primary packaging together, such as boxes or cartons. While form-fill-seal machines primarily focus on creating primary packaging, they can also be used to package products into secondary packaging by grouping multiple primary packages together and sealing them in a larger container. Overall, form-fill-seal machines are versatile and efficient packaging solutions that can streamline the packaging process and ensure products are securely packaged for distribution and sale.
