Your most important asset: Don’t waste it!.

1. Paper Trim Waste !
What is the cost of using incorrect measurements of paper widths?

3. Lets figure out this scenario:
A corrugated plant will consume 6,425 tons for the next period*.
This consume will be distributed in 400 different items.
* The period could be: monthly, quartetly, etc.

4. If you don’t know exactly how to calculate the accurate measures of
paper widths to ensure the least amount of paper waste, this is what
may cost to your company:

5. The initial, free, extra cost
Let’s figure out you of paper trim waste for
have an item with the first item is: 7.1 tons
this measures or $4,291* Dlls.
You customer needs
And you only have 50 k units.
paper in these
measures.
* $600 Dlls. per tonnage

6. I know what you are thinking:
why don’t you mix orders to
fill the space between the 80
and 97 widths ?
Because of the measures is difficult to combine orders above 71” and because of the
length is difficult to find orders to fill such a big quantity, among other requirements it’s
necessary to meet.

8. The cost for the second item is: 2.8 ton or $1,732* Dlls.
Oh, sorry, I’m forgetting to tell you about the Waste Factor and Trim Width. The totals Tons
Trim Waste are calculated with 7% of production waste and 2.7 cm (1.06 in) of normal trim.
This quantities may vary according the standards of each company.
* $600 Dlls. per tonnage

10. The cost for the third item is: .3 ton or $176* Dlls.
In this kind of orders you can do what ever you want, ok?, of course you need to reduce
costs anytime, but instead of spend time in the small orders, better review the percentaje of
waste of the large ones.
* $600 Dlls. per tonnage

11. And so on..
Remember, you should start with the items
of greatest impact on cost or productivity.

12. Applying the rigth calculations, it’s possible to identify and select the
optimal paper widths to buy paper for the next period.
These are not the Lotto numbers, ok ?, but have similar effects.
No other measures ensures the least amount of waste for those 400 items.
Really !…. No other ones.

13. Let’s calculate the same items with the optimal paper width
measures.

14. The cost for the first item is: .1 ton or $72* Dlls., when the paper widths are
the ideal measures.
* $600 Dlls. per tonnage

16. The cost for the second item is: 2 ton or $1,217* Dlls.
* $600 Dlls. per tonnage

18. The cost for the third item is: .7 ton or $406* Dlls.
* $600 Dlls. per tonnage

19. Please, take a deep breath.

20. This exercise shows the importance of analizing the top consumed items.
You may notice that the differences calculated in only 3 items are high-impact on
the cost and / or productivity.

21. There are other additional costs generated in the 9.404 m2, such as glue, transportation,
waste management, storage, salaries, etc.
This amount also affects the statistics of production, because it increases the square footage
produced. Since the trim is absorbed by the ducts and then mixed with other waste, it is
difficult validation of results per run.

22. There are additional costs of greater impact
that occurs when you run out of inventory
and it must be used the next one.
Similarly the costs associated
with paper surplus, which is difficult
to use for not having orders on
those measures.

23. You have the advantage to
choose the ideal paper
So, since you are
widths measures to ensure
planning the
the lowest amount of paper
purchase of paper,
waste
you can reduce costs.
And you have
pleeenty of time to
deal with unexpected
issues.
Human Expert
Intelligent system
And please, let the system to find matching orders, only for those
items with the lowest impact on cost / productivity, ok?`

24. Do you know how to calculate the ideal size of
each width ?
Are your paper widths aligned to the most
consumed items ?
Is it stable the consumption per width ?
Do you need to change your widths ?
