What is High Barrier Thin Wall Injection Molding Packaging?

Jul. 10, 2023

Ethylene vinyl alcohol (EVOH) is a barrier used in plastic food packaging to minimize the transmission of oxygen into the container in order to improve the shelf life. For food packaging containers, a thin wall indicates that the wall thickness is less than 0.025 inch (0.62mm), depending on the design of the containers.

In-Mold Labeling (IML) container

High Barrier Thin Wall Injection Molding Packaging refers to a specialized manufacturing process for producing food packaging containers using injection molding technology. This type of packaging is known for its thin walls and high barrier properties, making it ideal for preserving the freshness and quality of food products.

Injection molded packaging is created by injecting molten plastic material into a mold cavity under high pressure. The material solidifies within the mold, taking its shape and forming a rigid container. This process allows for the production of intricate designs and complex shapes with thin walls, which are essential for optimizing packaging efficiency and reducing material usage.

Food packaging containers produced through high-barrier thin-wall injection molding are designed to provide an effective barrier against oxygen, moisture, and other external factors that can degrade the quality and shelf life of food. The high barrier properties help in maintaining the freshness, flavor, and nutritional value of the packaged products.

In-Mold Labeling (IML) containers are a specific type of injection molded packaging that integrates labeling directly into the container during the molding process. This eliminates the need for separate labels, improving efficiency and enhancing the overall appearance of the packaging.

Thin wall packagings refer to containers with significantly thinner walls compared to traditional packaging solutions. The thin walls reduce material usage and allow for greater stackability and storage efficiency. Despite their thinness, these containers still maintain the required strength and durability to protect packaged food products.

In summary, High Barrier Thin Wall Injection Molding Packaging is a specialized manufacturing process that produces food packaging containers using injection molding technology. It offers thin walls, and high barrier properties, and can incorporate in-mold labeling, making it an efficient and effective solution for preserving the quality and freshness of food products.
