Sinstar Triplex solventless co-laminating machine

Sinstar Triplex solventless co-laminating machine

For flexible packaging industry, nowadays the competition is becoming tougher and tougher. Every enterprise involved is trying to find ways to have competitive advantages, including unique raw materials, high efficient internal management, advanced equipment and manufacturing technique.

TRI-1300A, the machine we demonstrate, is a new product grandly launched by Chongqing Sinstar Packaging Co.,Ltd. In 2023. We are quite sure that it will be a new force in the competition of flexible packaging industry.

 

Advantages of Triplex solventless co-laminating machine

Advantage 1 : Achieve industry highlight.

Compared to traditional simplex solventless laminator, TRI can do lamination of three layers structure at one time.

It expands the application scenarios of solventless lamination process.

and shortens production lead time.

Improves speed of enterprise turnover.

 

Advantage 2 : Solve the pain point of aluminium foil lamination

There will be no back penetration problem any more because the lamination of three layers structure can be done at one time and aluminium foil is the intermediate layer.

It means the requirement for less aluminium foil pinholes could be reduced.

And the technique requirement of solventless lamination process could be reduced as well.

 

Advantage 3 : Solve pain points of flexible laminate packaging industry

It can reduce the impact of moisture in the air on lamination

 

What will non solvent Triplex co-laminating machine create for flexible packaging industry?

Profit growth point 1 : production electricity cost

Three layers can be laminated at one time, resulting in a 30-50% reduction of power consumption per unit area.

 

Profit growth point 2 : curing room electricity cost

The power consumption for curing is reduced by 50% because you don’t need to do curing twice.

 

Profit growth point 3 : materials spending amount

Aluminium foil is expensive. By co-laminating process we can shorten the width of coating overflow zone by 5-8 mm which means reduction of aluminium foil consumption.

 

Profit growth point 4 : raw materials price

Aluminium foil pinholes are not problems any more and the requirement for aluminium foil grade can be reduced.

 

Profit growth point 5 : storage space

Co-laminating process can reduce space occupation of curing room and materials turnover space.

 

Profit growth point 6 : production site

Compared to 2 sets of simplex solventless laminating machines, triplex co-laminating machine reduces space consumption of production site by 40%.

 

Profit growth point 7 : labor intensity

Reduce labor intensity and transporting time for bringing materials between workroom and curing room.

 

Profit growth point 8 : overall efficiency

Lamination at one time, curing at one time, results in less production time, lower production cost and higher efficiency.

 

Advantages of non solvent low loading triplex co-laminating machine

Advantage 1 : process

Triplex co-laminating process does not require twice of lamination and curing.

Aluminium foil : low loading position, simple operation, saving time and labor

Aluminium foil : short path, about 1 meter’s flow length only

Aluminium foil : no coating, protected from the impact of high viscosity adhesive on the film edges, simplifying production process

Triplex laminator (compared to simplex solventless laminating machine), familiar equipment, familiar operation, familiar technology and familiar process

 

Advantage 2 : safety

No need for raw material especially aluminium foil to be transported to a high level for loading, avoiding the risk of material falling during transportation

Material does not need to be laminated at a high position, avoiding the danger of material releasing and falling

Low position loading, employees do not need aerial work certificate

Low position loading protects employees from risk of falling from high place

 

Advantage 3 : equipment operation

Familiar equipment, familiar operation, familiar technology and process

No need for high position loading, reducing labor intensity greatly

Materials can be handled at one time, avoiding transportation of materials for two many times

Low position loading makes threading of aluminium foil much easier

Low position loading provides more convenience for jointing materials

 

Advantage 4 : space consumption

The equipment is only 2.6 meters high, standard floor height of industrial building is enough, no special requirements

The height of machine is suitable for multi-storey structure industrial building and easy to install

The equipment is 8.2 meters long and 2.9 meters wide, increasing the utilization rate of floor space by 40%

 

Advantage 5 : adaptability

Suitable for both large and small diameters of materials rolls, one machine, full coverage

Suitable for lamination of aluminium foil and other substrates, one machine, full coverage
