Cotesa Packaging is dedicated to manufacturing plastic bags of the latest generation. They are susceptible to being molded by thermal processes, at low temperatures and pressures. They present a series of very useful physical and chemical properties in the production, packaging and packaging of various products. Plastic materials are organic substances characterized by their macromolecular and polymeric structure; that according to their chemical composition will have different properties from which their applications derive.

At Termopack we are developing containers that will allow us to know if the product they contain has suffered some type of incorrect handling during transport or distribution and storage (vacuum losses, breakage of the cold chain

The increase in demand for prepared or precooked dishes has led to a revolution in the world of packaging. For this type of product, we develop materials that preserve their qualities, that are resistant to microwave heat, and that are easy to transport.
For food packaging there are a variety of materials available on the market for this purpose, for example: glass, paper, metal, and very particularly the use of plastic materials; Whether it is a can, bottle, glass jar, or a cardboard container, it helps to protect food from contamination by microorganisms, insects and other contaminants.

In addition, it preserves the shape and texture of the food it contains, prevents it from losing flavor or aroma, prolongs storage time and regulates its water or moisture content. The packaging also allows manufacturers to offer information on the characteristics of the product, its nutritional content and its composition.

In response to the fast pace of modern life, there is a wide variety of ready-to-cook foods on the market, even without the need to remove them from the packaging.

In recent years, food packaging systems have evolved in response to consumer demands (in terms of expiration, freshness, appearance, etc.) and changes in lifestyle (greater demand for products that are comfortable to consume and semi-processed). Social changes such as the globalization of markets have also imposed higher demands on the freshness and durability of food.

The growing demand by consumers for increasingly "natural" products (less processed, without preservatives, etc.) and of higher quality, but at the same time with longer shelf life, has caused packaging to acquire more than ever a fundamental role in food preservation. In addition, there is a growing concern about food safety, both on the part of companies, institutions or consumers themselves.

In this area, containers are being developed that will allow us to know if the product they contain has suffered some type of incorrect manipulation during transport or distribution and storage (loss of vacuum, breakage of the cold chain, etc.). On the other hand, consumer demand for convenience, with less and less time available, has promoted the boom in the sale of ready-to-eat products (sliced, fresh-cut vegetables and fruits, etc.).

For this type of products, materials have had to be developed that preserve their qualities, that resist the heat of microwaves, and that are easy to open and transport. This trend towards comfortable packaging can also be observed in the proliferation of easy-open packaging, the possibility of closing the packaging again once opened, etc.
