What is the reason why glass milk bottles last?
Speaking of glass milk bottles, does anyone find it expensive and time consuming to recycle and clean them? With all the convenient features offered by modern cartons, why is there still any glass bottle being produced today?
Economically and technically speaking, two of the more popular types of packaging on the market today are Tetra Pak and glass bottle packaging. Tetra Pak is manufactured by Swedish Tetra Pak; their packaging materials and machines come at a higher cost.
First is the low threshold glass bottle filling technology, widely used in China for years and boasting mature yet cost-effective methods of cleaning, filling and pasteurization - ideal given their short shelf lives and consumption characteristics.
The second benefit is recycling of glass bottles: After you order milk, drink it out of its bottle! This helps lower costs further. Finally, using glass bottles instead of plasticizer-containing bottles reduces risks for contamination with plasticizer.
Glass milk bottles serve a twofold purpose.They're pasteurized and consumed within 24 hours of ordering them for sale - most sales occur through this model.
On one hand, many consumers believe that milk produced on that particular day should be taken immediately for consumption as pure fresh nutrition; on the other hand, glass pasteurization is commonly employed when pasteurizing glass bottled milk; heating at lower temperatures over a longer time provides for a mellower taste while simultaneously maintaining more nutrients.
