Start from the closing area of the bag instead of the weight
Clip size for coffee, doypack and kraft bags; The mouth width is selected based on the folding style and the allowance left for folding. Defining the package as 250 grams or 1 kilogram is not enough on its own. The same filling amount can be presented in bags with different width, height and bellows dimensions.
Doypack closure clip, it is evaluated to close the mouth of the bag and re-open and use it when necessary. When choosing, it should also be clear how the clip will be applied to the package. The requirements for a clip that works with the fold-over top may differ from the roll-up bag opening.
Check the folding allowance on the full package
The height of the empty bag and the free upper part remaining after filling are different. Determine the area where the clip will be placed in the packaging prepared with the normal filling amount. Note the number of floors and the approximate width of each floor; Use the same movement during evaluation.
If the bag has a zipper, valve or other closing detail, show its location in the photo. Determining where the clip will sit relative to these sections is more revealing than simply choosing the product size. Evaluate the design requirements together before modifying parts of the existing packaging design to accommodate the clip.
Separate packaging structure with kraft appearance
Two Kraft-looking bags may not have the same layer structure or folding behavior. The outer appearance does not tell all the technical features of the bag. Use the actual packaging sample at hand when selecting clips; Don’t rely solely on the catalog photo.
While one bag folds easily, the other may tend to open after folding. This difference affects the application of the clip. When the bag material, filling and folding method are recorded together, it becomes clear which product was chosen and why.
Initial sealing and reclosing are different stages
The clip can help the user reseal the opened package. However, it should not be assumed that the bag has the same function as the initial closing system. Mechanical clip sealing by itself does not validate claims of airtightness or a specific shelf life.
If the packaging uses a different initial closure method, explain how the clip is activated during subsequent use. The user’s ability to store the clip without losing it, easily reposition it, and fold it again is also part of the product experience. Don’t limit this check to just the person doing the initial shut-down in production.
Brief comparison for product selection
| Variable | question to ask | Information to be added to the request |
|---|---|---|
| Bag size | Which section does the clip cover? | Mouth width and photo |
| Filling | How much free space is left at the top? | Normal filling quantity |
| folding | What is repeated closing motion? | Number of floors and application photo |
| presentation | Is clip visibility important? | Color or finish reference |
| Application | Will it be closed manually or by the system? | Current method and model if available |
Color selection and package view
You can choose the clip color along with the product family, packaging printing and package types used in sales. If there is a different expectation from standard colors, please share a physical reference. Keep the color description and the product’s material and size description separate; visual match does not replace technical match.
If more than one type of coffee is sold in the same packaging, clip colors can help differentiate the type. This is a design choice; You must specify the order quantities of the colors separately. Custom color and cutting guide details claim preparation.
An example evaluation flow
Imagine looking for a common clip for coffee bags with two different mouth widths. First prepare each bag with its own filling. Evaluate the same clip candidate with the same folding motion on both packages. Do not conclude at first glance that what is adequate in one package is also suitable in another.
Record closing appearance, loosening, opening, and reapplication observations separately. If you need to change the clip length in the measuring guide Use definitions. In coffee packaging solutions You can examine the relevant product families together.
