Does Plastic Packaging Maintain the Freshness of Food Items?

There are packaging service providers who are giving a variety of options to food & beverage. However, there are certain essential things to know when choosing the same. As we all know not every plastic film packing in the market would be the right product to invest in. 

The different densities of packaging materials are suitable for various categories of food items.

For the bottles that store liquid such as water, juices, or milk, it is recommended to use high-density polyethylene. Furthermore, these are used in cereal box liners & the retail sector for bags. They are sturdier and cannot easily be torn apart. In addition to the above, a solvent-resistant nature makes these a preferred choice among others.

Another one is the low density which while sealing involves heat. Next time, while buying bread, remember to choose those being packed by using low-density polyethylene. Moreover, the flexible lids that are convenient to use are also manufactured utilizing the respective polyethylene.

Then comes polypropylene which generally is used in manufacturing the bottles that contain food & salad dressing liquids. The yogurt container picked from the stores is molded with the respective material.

Plastic-based packaging plays a crucial role in maintaining the freshness of food items through various mechanisms. Here are 10 ways how plastic-based packaging achieves this:

Barrier Protection: Plastic packaging forms a barrier that prevents oxygen, moisture, and other gases from permeating through, thus slowing down the oxidation process that leads to food spoilage.

Extended Shelf Life: By creating a controlled environment, plastic packaging helps extend the shelf life of food items, keeping them fresher for longer periods.

Protection from Contaminants: Plastic packaging provides a physical barrier that protects food from contaminants such as dust, dirt, and microorganisms, reducing the risk of spoilage and foodborne illnesses.

Modified Atmosphere Packaging (MAP): Some plastic packaging is designed to modify the atmosphere surrounding the food by adjusting the levels of oxygen, carbon dioxide, and nitrogen, which can inhibit microbial growth and enzymatic reactions that cause spoilage.

Moisture Control: Plastic packaging can regulate moisture levels by either blocking moisture from entering or allowing excess moisture to escape, depending on the specific requirements of the food product.

Temperature Control: Plastic packaging helps to insulate food items, maintaining optimal temperature conditions during storage and transportation, which is crucial for preserving freshness.

Protection from Light: Certain types of plastic packaging are designed to block out light, which can cause food to deteriorate due to photochemical reactions. This is particularly important for light-sensitive products like dairy and certain meats.

Tamper-Evidence Features: Many plastic packaging solutions include tamper-evidence features such as seals and closures, ensuring the integrity of the package and assuring consumers that the food inside is fresh and safe to consume.

Portion Control: Individual plastic packaging portions help maintain freshness by reducing exposure to air and contaminants. Once opened, the remaining portions remain sealed and protected until consumed.

Convenience Features: Plastic packaging often includes features such as resealable zippers and easy-to-open seals, allowing consumers to conveniently access the food while preserving its freshness between servings.


These methods demonstrate how plastic-based packaging serves as a versatile solution for preserving the freshness and quality of food items throughout the supply chain, from production to consumption. 

In a nutshell, product packaging is not just for keeping the product safe from outer hazards and keeping it fresh for a longer time. It is meant to serve various purposes which include advertisement of the product, the safety of the product, and brand establishment information. This is the reason why brands are quite obsessed with their product packaging and spend millions of dollars just to make it attractive and informative.
