PET (Polyethylene Terephthalate) Cup water , which is produced by a horizontal form fill seal machine , is now widely available for sale, and its consumption has risen dramatically over the past years.
The growth in cup water and carbonated drinks demand is influenced by three principal public concerns: declining quality of city water supplies, contamination of groundwater sources, and a generally increased interest in personal health.
Bottled water and PET water cup are also regarded as a fashion accessory for many consumers. There is a general perception that bottled water and cup water is safe, natural, and free from additives.
The major deterioation risk of bottled water and cup water is microbial growth. There is also risk of loss of content, taste loss, change of appearance, contamination…
What is a form fill seal machine ?
Form Fill Seal (FFS) machines are a type of packaging machines which forms, fill and seal a package on the same machine at the same time. There are two major types of form fill seal machines one is vertical form fill seal (VFFS) and the other is horizontal form fill seal (HFFS) machine.
Basically form fill seal machine forms the plastic sheet with the help of heat to a desired shape and then fills the liquid inside after that seals and finally cuts to a seperate cup.
What is the usage of a horizontal form fill seal machine ?
Horizontal form fill seal machines are generally cam driven machines leads a very high output and able to fill low, medium and high viscous fluids like water, juice, carbonated drinks, ketchup, mayo, chocolate paste, yoghurt, honey, jam, oil, butter, margarine, spread cheese…
What is the cup water machine ?
Cup water machine is the horizontal form fill seal machine that uses PET (Polyethylene Terephthalate) as plastic sheet film to form to a desired cup shape ,often 200 ml to 250 ml water cup, fills the water in this cup then seals and cuts to seperate plastic water cups.
PET (Polyethylene Terephthalate) Water Cup Performance
All plastics are permeable to some extent to gases, and most bottlers will require a performance that is tolerable with respect to the required shelf life. For carbonated beverages the specified loss rate is typically 15% of the CO2 for water cups around 10 weeks.
PET shows one of the highest CO2 gas barriers for all plastics used for packaging and is an order of magnitude better than polyolefins or polycarbonates.
