Packaging Machinery - News, Technology and Reviews

Coffee packaging should have the convenience features of the customers such as easy open sealants, filaments, pour spouts, and re-closure systems. Coffee packaging should ensure the preservation of the quality of the coffee and retain the flavor of the coffee .The package should also fight oxygen which is the enemy of coffee. Coffee packaging requires advanced design and technology for high performance.

Coffee Packaging Materials

• The material used in coffee packaging is very common in varied products.
• They are generally plastic, glass, aluminum foil, or multi layer material to protect the product against air.
• The best traditional way to pack roasted or grounded coffee is the butter-paper pack, which is considered as the cheapest packing material for coffee packaging
• Triple laminate materials are the next packing material, which make the packaging sturdy, for mass marketing and transportation.
• Foil based packages ensure longer protection of the product.

Technology and Machinery Used in Coffee Packaging

• The very first place for coffee packaging for years stays with the vacuum hard packaging process.
• Generally, automatic fill and seal machines are in use for coffee packaging.
• Machines based on the one- way breathing valve technology are common in use on coffee packaging to release carbonic-oxide given off freshly roasted coffee without exposing the product to oxygen.
• Application of ‘Sealant Technology’ is useful in coffee packaging machineries to make it easy to open the package without using scissors. Machines like Automatic sealers need specially designed system for use with barrier laminates to insure the hermetic seals.
• Connor package is another unique package that transforms a flexible laminate into a semi-rigid flexible box fitted with a simple peel seal opening a degassing valve and an enclosable flap.
• Reseal able zip lock packaging machines are also one of the innovative techniques in coffee packaging.
• Multi-layer laminate allows ground coffee pulled to full vacuum while maintaining a soft, smooth appearance on the external package.
• Individual coffee package refers to a common package generally known as “pod” or capsule which contains a dose of roasted and ground coffee sufficient to provide one or more cups of coffee when put into the extraction chamber to make espresso coffee. The pod is a dose of coffee compressed between two layers of paper through which water can readily percolate or some other equivalent material.
  Various other machines are in use to incorporate vacuum, gas flush, hot fill, retort, and aseptic technologies.
