Doypack is a sachet with a bottom fold and a particular outlay of stiening welds which create a modern and universal packaging. Its main advantages are: displaying the product in an upright position, a large surface for printing, a possibility of welding in a string closing or a topper, a price lower than that of alternative packaging systems. These packagings are used for both manual and automated packaging of foodstuff (i.e. coffee, tea, spices, dried fruit, nuts, juice, mayonnaise, candy, etc.), seeds, chemicals, tobacco, etc. Doypack sachets are available in a variety of sizes, with or without a string closing, a topper, made out of materials of different colours, thickness and structure.
