Introduction to Polyvinylidene Chloride

Polyvinylidene chloride (PVDC) is a synthetic thermoplastic polymer that is primarily used in the production of food packaging materials due to its exceptional barrier properties. It was initially developed in the 1930s and has since become a critical component in preserving and protecting food products. The chemical formula for PVDC is (C₂H₂Cl₂)_n, and it is generally produced through the polymerization of vinylidene chloride.

Applications in Food Packaging

PVDC is renowned for its low permeability to water vapor, oxygen, and aromas, making it an ideal material for food packaging. It acts as an effective barrier against external contamination and helps in extending the shelf life of perishable goods.

Barrier Properties

One of the significant advantages of PVDC in food packaging is its barrier properties. It provides a moisture vapor transmission rate (MVTR) of approximately 0.05 g/m² per day and an oxygen transmission rate (OTR) of 0.5-0.8 cc/m² per day at 23°C and 0% RH, which significantly helps in maintaining food quality.

Common Uses

PVDC is ubiquitously used as a coating on various substrates such as films and foils. It is often employed in packaging for items like meats, cheeses, snacks, and confectioneries. For example, PVDC-coated films are commonly used in vacuum packaging and modified atmosphere packaging (MAP) to maintain freshness.
