فارسیPetroleum Wax Usage in the Packaging Industry
، The four major industry segments in which petroleum wax and/or wax blends are used are as follows:
- Folding Cartons
- Corrugated Containers
- Flexible Packaging
- Paper Cups and Food Containers
The following is a summary of the many advantages wax offers to the packaging industry.
- Water Resistance and Water Vapor Resistance
Water and water vapor resistance is the most important property associated with paraffin wax in conjunction with paper. - Gas and Odor Barrier
In addition to good protection against moisture vapor, paraffin wax is a good barrier against odor and gas transmission. It is this property which protects products against loss of flavor and odor and from contamination by foreign odor. - Economy
Petroleum based waxes are very economical water-resistant materials and their low viscosity requires relatively minimal machinery cost for application at high speeds. - Purity
Many grades of petroleum based wax are food grade, tasteless and odorless.
In addition to these advantages, petroleum wax can be blended with other waxes and additives and/or physically modified via mechanical means to provide the following important properties in paper packaging:
- Heat Sealability
- Hot Tack
- Gloss and Gloss Stability
- Blocking
- Friction
- Scuff Resistance
- Grease Resistance
