JANDI’S JIT T-SHIRT BAG MAKING LINE

– Green Design on Plastic Bag Making Machine

The advantaged features of JIT T-shirt Bag Making Line :

• Big saving on Power Consumption
• Less working space required for the same output
• Less workers required for the same output
• Less Human Error and minimize the management required
• ower Material Cost for making T-shirt Bags
• Best partner in using Bio-Degradable material for T-shirt Bags
• Better sealing quality, very strong sealing line
• Less Carbon Emission, less Carbon Footprint

As a Plastic Machinery Manufacturer, JANDI’S presented, since 2013, a patented and green design machine which makes no waste plastic left during processing.

The traditional way to produce T-shirt bags, it takes 100 tons of material to make average 85 tons of end products, and has to recycle average 15 tons of waste film from die-cut. But, by using JANDI’S JIT it makes nearly 100 tons of end products from the same amount of material.

In making the T-shirt/Shopping bags, the general steps are as followings: First is to Blown Film, Second is Printing, and Third is to seal & cut the film into individual bags, and followed by the waste recycling of the die-cut. Which also takes a lot of space for storage and handling works in-between each process (also refer to attachment – 001)

The die-cut is the waste film cut-off from the bags to make the T-shirt form, and it is between 12% up to 18% of a plastic bag, in average there is 15% die-cut from each T-shirt/Shopping Bag. The recycling of the die-cut is a crucial point to the plastic bag manufacturing, which not only examines producers’ management and technology, because the colors, mixed material, cleanness of these die-cut could change the end products. But also increase a lot the power consumption & carbon emission during the recycling of the die-cut (crushing, washing, melting & pelletizing).

There is additional labor cost and processing cost to recycle the die-cut, but JIT runs the Blown film, Printing, Bag making, all in line, and reuse the die-cut on line during the production, make the end produce immediately, do not need any space to storage the semi-finished products between each process and has no additional cost for collecting, sorting, storage, handling in the recycling of the die-cut and to re-mix the recycled pellets with raw material. (also refer to attachment – 002)

Comparing with the traditional way, JIT save up to 25% power consumption for the complete production and recycling process on T-shirt bag’s production. (also refer to attachment – 003)

In Traditional way to make T-shirt bags, first is to blown the film, then printing, then to make sealing & cutting :

For Blown Film :

Usually to make a film roll will take about 4 to 6 hours, depends on the diameter of the roll, and usually a bigger diameter also means less change-over and less waste in production.

And, the problem could be happened in the blown film process are :

-        The film size (width & thickness) is not correct

-        The color is not correct

-        The film is not surface-treated, by corna treater, to be ready for printing

For Printing :

It takes about 3 to 4 hours to print each film roll

The problem could be happened in the printing process are :

-        The printing quality is not qualified

-        The ink is not dry enough before rewind

-        The printing length is not stable (problem in Tension Control during printing)

For Bag Making :

It takes about 2 to 3 hours to cut & seal each film roll for making the bags.

The problem could be happened in the bag making (sealing & cutting) process are :

-        The bag length is not uniform because of the printing length is not stable

-        The sealing is not strong enough because of the abnormal operation in blown film.

Altogether, blown film 4 to 6 hours, printing 3 to 4 hours, bag making 2 to 3 hours, it is about 9 to 12 hours from the raw material to the end products, only after all these times then the quality of the end products could be examined. If there was any mistake during the processing, you might lose a lot from all these production.

By JIT, you can see and check the finished product as soon as the machine has been started up, which save you a lot of trouble and reduce all the human errors could be happened during the processing, minimize the management in production.

Green manufacturing & pollution caused by plastic film/bags are the major concerns about the environment protection. Bio-degradable material is one of the success solutions for these issues. However, one of the concerns, in using Bio-degradable material, is the cost is 2- 3 times higher than the normal plastic resin. And, it is also more difficult to recycle and reuse the Bio-degradable material, this makes the cost to Bio-degradable T-shirt/shopping bags become even higher. This makes the promotion of Bio-degradable material even harder. When using JIT, to produce T-shirt bags, the 12-18% die-cut is reused on line, this save partial the cost and difficulty in using bio-degradable material.

JIT in-line production process seals the bag when the film is still hot, the sealing line is melted together naturally, unlike the old traditional way has to make the sealing on the cold film, which requires higher temperature to melt/seal the film together and the sealing could become embrittlement cause the bags broken on the sealing line.
