Why are fruits packed in plastic?

Fruits wrapped in plastic

It is in 1911 that the flexible packaging industry was born. Simultaneously, in France and Germany, the manufacturing process of a regenerated cellulose film was developed: the well-known CELOFAN.

2. Flexible packaging: requirements and propertiesFlexible packaging must fulfill a fundamental mission: to preserve the product inside from the moment it is packaged, during transport, storage, distribution and display, until the moment it is opened by the consumer. Many of the desirable properties obtainable from flexible packaging are closely related to the properties of plastics.

From the standpoint of packaging applications, let’s look at some important properties and why they are significant: Mechanical tensile strength This property often determines the amount of plastic material needed to form the wall of a package. Mechanical resistance to perforation.

7. Applications to the food industry Dairy We discussed milk powder earlier. Fresh milk must have an economical and at the same time protective package; usually a coextrusion of black pigmented LDPE is used for the inner side in contact with the product (light protection) with white pigmented LDPE as the outer and printed side. Another possibility is packaging in Tetra Pak or Tetra Brik.

Why fruits should not be stored in plastic bags

In the fruit and vegetable industry, the packaging process is the most important phase in the market cycle. We need to know the strategies to achieve a perfect packaging process. If we get the packaging right, fresh and fresh-cut fruits and vegetables will stay fresh and fresh for longer. For this to happen, three factors must be taken into account: humidity, temperature and the atmosphere with its modifying components.

Fresh vegetables and fruits are an attractive part of our diet. However, these foods have a rapid degeneration, decomposition and aging. A poor appearance of these products influences the moment of purchase. The consumer will not want food with a dubious appearance and the seller will not be able to sell these products and consequently, his losses will increase. Therefore, the approach of including good packaging for fruits and vegetables in the transport process should be paramount. Although there is a prior cost for providing quality packaging, this will compensate in the quality of the goods transported and their subsequent marketing.

Because fruits and vegetables are not wrapped.

Of course, without ever forgetting the glass, although most people did not use it because it was more expensive and heavy.    We have already talked about the change that the market is undergoing and the fact is that every day consumers are more concerned about knowing the product they are going to consume. In addition, many companies, such as Quesería La Antigua, are committed to recycling and reusing packaging, guaranteeing sustainability and improving the environment.

This implies knowing what its ingredients are, where it is made and also deciding the material of the container that contains it. And at this point we have something to say, since a food packaged in a glass container is not preserved in the same way as in a plastic one.

Most of the containers we use are made of plastic, and we must be careful with this material. Some of them, when heated at high temperature, can be harmful to health. Causing some alterations in the nervous system, prone to cancer and sterility.

Overpackaged

Bulk fruit (as it has been sold all its life) is in danger. Apples, bananas, strawberries, legumes and, in fact, anything, suddenly appear in a plastic bag or net, which also conditions the customer in choosing the quantities he wants to buy. You can no longer choose how many units you want to take, you have to buy the whole package.

In the bakery and confectionery section, there is hardly any product that is not doubly wrapped in plastic, such as the bags of muffins, which are packed one by one in this material, and then put all in one bag. The examples are almost endless.

Lidl, for its part, is committed to guaranteeing 100% recyclability by 2025 and to reducing the amount of plastic used in its own-brand packaging by 20%. Mercadona has already replaced plastic swabs with biodegradable cardboard ones, and by 2020 will replace disposable plastic plates, cups and cutlery with reusable ones or ones made of other materials. It does not give dates for more ambitious goals: “It is something that we cannot decide ourselves, but in collaboration with packaging suppliers and the packagers of our products,” the company clarifies.
