New trend of tea beverage packaging materials
some manufacturers use non-heat-resistant PET bottles as tea beverage packaging containers, but the quality of most products is not very good, during the shelf life, there will be serious Browning, precipitation and deterioration of tea color. This is because most manufacturers use mineral water filling line as the production equipment of PET bottled tea beverage, but at present, the equipment of mineral water filling line is not suitable for aseptic filling of tea beverage or hot filling at about 60℃, and its stability is poor, the filling environment is also unstable, prone to secondary pollution, resulting in excessive bacteria, tea deterioration.
at present, Taiwan-funded enterprises basically use sterile Tetra Pak as tea beverage packaging, such as unification, Master Kang, life, etc, in addition, such as Sun Risheng, Huiyuan, Shenhui and huierkang are also adopted. These manufacturers have relatively strong financial strength and rich experience in tea beverage production. Their products have good taste, stable quality and optimistic sales situation, and have a high market share in China's tea beverage sales in recent years.
