How Does Vacuum Packaging Extend Shelf Life?

Vacuum packaging removes most of the oxygen around a product and then seals it inside a barrier film. By lowering residual oxygen and isolating the product from moisture, odors, and airborne contaminants, the biochemical and microbial changes that cause spoilage slow down dramatically.

What Is Barrier Film and Why Is It Important in Food Packaging?

Barrier film is a multilayer plastic or paper–plastic laminate engineered to slow or block the transmission of gases, water vapor, aromas, oils, and light that can degrade food. By controlling the movement of oxygen, moisture, and other small molecules, barrier films preserve flavor, color, texture, and nutrition—directly extending shelf life and protecting product safety from the factory line to the consumer’s kitchen.

How Do Oxygen and Moisture Barrier Properties Affect Food Product Freshness?

Food product freshness is one of the most critical factors in customer satisfaction and brand reputation. Packaging plays a central role in preserving that freshness by controlling the internal atmosphere of the package. Among the physical attributes of packaging materials, oxygen and moisture barrier properties are paramount in determining how long food maintains its quality, safety, and sensory attributes during storage and transit.

What Are the Differences Between Co-Extrusion Bags and Laminated Composite Bags?

In modern flexible packaging, co-extrusion bags and laminated composite bags are two of the most widely used options for protecting products during storage and transportation. While both bag types achieve multilayer performance and barrier properties, they differ fundamentally in their manufacturing methods, material structure, mechanical behavior, performance, cost, and common applications.

How to Test Puncture Resistance and Sealing Strength of Barrier Films?

Barrier films used in packaging must not only provide excellent resistance to moisture, oxygen, and contaminants, but also withstand physical stresses and maintain secure seals throughout handling, transportation, and storage. Two key performance indicators for barrier films are puncture resistance and seal strength.
