A sachet is a bag that closes airtight.
Sachet is a word that is not part of the dictionary of the Royal Spanish Academy ( RAE ). It is a French term used to refer to a small bag that, when closed hermetically , houses a product inside.
Once a sachet is opened (that is, its airtight seal is broken), what it contains must be used at once or as soon as possible. This need to use the product quickly is due to the difficulties in re-closing the sachet or, in certain cases, because the product can spoil.
Some of its physical characteristics are its shape (typically rectangular), its texture (which can be smooth, especially for food, or rough, for personal hygiene products), its sheet -based composition and its hermetic closure. Black is usually used inside to prevent light from making direct contact with the product it contains. The most used materials for its manufacture are aluminum, paper and certain plastics.
Uses of the sachet
Typically, these containers contain liquid, creamy or gel products. In the case of food , milk , yogurt , mustard , ketchup and mayonnaise ( mayonnaise ) are some of the products that are usually offered in sachets.
Their use is very common in fast food chains, since they allow these products to be marketed in small proportions, ideal to accompany a dish without it being wasted. In these cases, stores do not usually charge an extra fee for each sachet, although some do, to avoid abuse by consumers (such as ordering many more than they need and then taking them to use at home. ).
Milk and yogurt, for example, are sold in one-liter sachets . As many times the contents of the sachet are not used up as soon as the container is opened, there are containers known as sachet holders to store the opened sachet in the refrigerator (refrigerator or refrigerator).
Shampoo, cream rinse and liquid soap can be presented in sachets.
Conservation
A fairly widespread custom to preserve the sachets once opened is to place them in the jugs that are normally used for water or juice.
It is a cheaper alternative, since it avoids the purchase of a very specific product that may have a higher price simply for this reason, or cost the same but not be useful for anything else: although there are sachet holders that look Almost identical to a traditional jug, some do not have a handle and others have various holes in their structure, which make it impossible to use them to contain liquids.
Hygiene products in sachet
Liquid soap , shampoo and cream rinse are also usually offered in sachets. In these cases, the usual thing is that they are very small sachets that are given as a free sample so that a consumer can get to know the product and, if they like it, then buy a larger container . The shampoo sachet or the cream rinse sachet can also be useful on a trip , as they are easy to carry.
In hotels, for example, it is normal to find toiletries in sachets, such as shampoo and soap, and in this case the advantages of the format are the assurance that the products are not wasted (as mentioned above with respect to sauces in food stores) and also hygiene , since each customer receives a hermetically sealed envelope , which he himself will open and throw away once he no longer wishes to use it. It wouldn't be in keeping with the times to require them to share a bottle of shampoo with people they don't even know.
