City-Based Decision Matrix for PO and EVA Selection: Practical Guide for Istanbul, Izmir and Kocaeli
EVA and polyolefin hot melt selection is not based on the city name; It is made according to the packaging surface, line speed, open time, temperature resistance, odor and color expectation and application equipment. The exact choice should be verified by the manufacturer's technical data sheet and actual line testing.
There is no single order of superiority between PO and EVA that is valid for every application. The right product; It is selected by evaluating the cardboard or film surface, line speed, open time, heat resistance, odor-color expectation and cost target.
4 elements of establishing the decision matrix correctly
- Product turnaround speed:Which product is switched faster?
- Material condition:What is the surface structure and storage conditions of the cardboard or film?
- Maintenance window: Nozzle cleaning frequency and operator access.
- Repeat success: Is it stable on the second try with similar settings?
First suggestion by city
Make your selection based on your process goal, not the pivot table. For example;
| Situation | Preference | Reason |
|---|---|---|
| Standard case and box closure | EVA or PO | Verified by surface and line testing |
| Low odor and light color expectation | Appropriate PO options | Technical specifications of the product are checked |
| Fast line with short open time | EVA or PO suitable for the application | Machine and compression time are decisive |
| Heat resistance priority | Selection according to technical sheet | Service temperature is verified on a product basis |
Quick-check checklist
- Clarify target metrics (quality, speed, consumption).
- Get mini verification with first 20 tracks.
- Compare with the city's ambient trend on the same day
- Review the product comparison after three days.
Technical verification with product pages
- Jowatherm PO 851.10 product page
- EVA hot melt technical comparison
- Technical details of packaging glue
- Hot melt product selection guide
One line answers
- How are PO and EVA selected? Surface, speed, open time, service temperature and application test are evaluated together.
- Does the city directly determine product selection? No; Decisions are made on a product basis by measuring facility and material conditions.
- Where is technical information verified? The relevant product page, current technical sheet and field trial are used together.
City-Based Decision Matrix for PO and EVA Selection: Practical Guide for Istanbul, Izmir and Kocaeli hakkında merak edilenler
PO or EVA, how to decide?
The decision is made with metrics: consumption stability, speed variation and city conditions are reviewed together.
Which product stands out for Istanbul?
There is no suggestion per se; Humidity and speed change are evaluated together and the first mini test result is obtained.
In which metric is the Izmir line sensitive?
The combined change in open hold and speedup appears faster; Therefore, first hour monitoring is increased.
Which point is important in the election in Kocaeli?
Number of successful checks and number of interventions after product transition.
How many days of trial are required after the decision?
Generally, the permanence of the decision is measured in 2–3 shift observations; If necessary, a third evaluation is made.
Where to verify technical reference?
It is updated by comparing it with the relevant product technical sheet and production application parameters.
