Fortunately, this is not a very polluting material, since its origin is essentially natural, it is made with silica, but it is important to reuse resources to minimize the environmental impact produced in the production processes of packaging. We tell you how!
Take note of these alternatives: we find them very original and, in addition, they do not require a great deal of work to put them into practice. You can spend a nice afternoon with your family or relax decorating your home while contributing to maintaining the health of our planet. Are you up for it?
It is essential to be careful in these processes to prevent the glass can break and someone is cut, but in general you can prepare very interesting activities to share with family and take advantage to contribute to the sustainability of the planet. Do not you think a fantastic initiative?

 Plastic containers have been used as a substitute for glass or metal containers in beverage packaging for several decades. The most common plastic used in the manufacture of beverage containers today is polyethylene terephthalate (PET). Containers made from PET are transparent, thin-walled and have the ability to maintain their shape by withstanding the force exerted on the container walls by their contents. PET resins are also reasonably priced and easy to process. PET bottles are generally manufactured by a process that includes blow molding of plastic preforms that have been made by injection molding the PET resin.
 Advantages of plastic packaging include lighter weight and lower breakage compared to glass, and lower overall costs when taking into account both production and transportation. While plastic packaging is lighter than glass, there is still great interest in creating the lightest possible plastic packaging to maximize savings in transportation and manufacturing costs by making and using containers that contain less plastic, while exhibiting good mechanical properties.

At the corporate level, the trend towards concentration of capital is clearly evident in soft drinks, taking into consideration that the sector is mainly dominated by foreign capital companies that are managed by their parent companies, while local companies that produce global brands do so under the franchise system.
Similarly, there has been a growing concern for health care and esthetics, which has led millions of people to change their consumption habits. The result was an increase in the consumption of energy waters and juices, as well as low-calorie soft drinks, as opposed to other products with higher calorie levels.
What is noteworthy is that in the face of changes in consumer tastes and the multiplicity of options on the market, the share of traditional cola-flavored beverages has been losing preponderance to other flavors. Coca-Cola Co., PepsiCo Inc. and Dr. Pepper Snapple Group Inc., leaders in this type of soft drinks, have had trouble reversing the decline in the consumption of soft drinks in the United States, where buyers are increasingly opting for water, coffee and other alternatives.

The glass used in the manufacture of bottles is of the soda-lime type, where the differentiating characteristics of these containers are: the color, the type of applicable stopper-cap (which will depend on the type of mouth to be used), as well as the choice or not of protective capsules for its closure.
One of the advantages of glass bottles is the better preservation of the aroma of the product contained, especially in prolonged storage, since glass is impermeable to gases, vapors and liquids.
The base of the bottle is a fundamental element, since a great part of its resistance and balance depends on it and on the thickness of the walls of the glass bottle. It must contain the series of references detailed below;
Depending on the initial technical specifications of the bottle, the type of nozzle to be used will be selected. There are very complete regulations concerning the different types of nozzles. Below are some examples of the most common types of nozzles for glass bottles;
