Hybrid styrene film

Hybrid styrene film is the layer of PET and PS, and has the advantages of both PET and PS.
According to customer's application and required performance, we have several grades and meet the various needs that changes from day to day.

Item	PS	Hybrid styrene	PET
Layer composition (Diagram)
Features	Mostly used for shrink label in Japan	Original material of Gunze	Used for applications that take advantage of resin characteristics
Advantage	Shrink appearance, perforation suitability	Shrink appearance, perforation suitability, heat resistance, content resistance, stiffness	Heat resistance, content resistance, stiffness
Disadvantage	Heat resistance, content resistance, stiffness	―	Shrink appearance, perforation suitability

High shrink in super low temperatures (For hot air tunnel) Type HSAR

Advantage

Super low temperatures	shrink with great appearance to bottles having low heat resistance
High shrink	shrink with great appearance to the neck of the bottles

Application

• Homecare products (Detergent bottles, trigger spray bottles), food

High shrink in low temperatures (For steam tunnel) Type HSTN

Advantage

Low temperatures	Since it starts shrinking in low temperature, high speed of shrinkage can prevent the occurrence of wrinkles.
High shrink	With high shrinkage it can apply to complex-shaped bottles.

Application

• Food (Freshness preserving bottles, bottles with cap-seal)

Polyolefin shrink film

• Gunze has developed polyolefin shrink film for label with original technology, in order to be used for an application which requires cold resistance or chemical resistance.
• Density separation recycling is possible since the density is lower than 1g/cm3.
• Please refer to the new polyolefin page to see our advancing effort of polyolefin shrink label.

Application

< Frozen beverages, homecare products >

PET shrink film

• With the advantage of PET material which has stiffness and content resistance, it is also used as the packaging materials other than labels.

Application

Type	TAS	TRS	TNB
Application	For general labels	For round shrink wrap bag	For lids of hot pot noodles
Advantage	General use	High in thermal cutting	Anti-fogging
