In Detail:
APPEARANCE
The closure Herma labels are made of semi-transparent material, such as seen in the photos above.
LABEL
Labeling ballpoint, rollerball pen or felt-tip pen is fine. Nothing smeared. So the etiquette label, peel and seal the freezer bag so with date.
The etiquette keeps well and, above all, larger packages such as 1 kg bag coffee beans reliably sealed.
Adhesive force
From ausgelobten by the manufacturer "extremely strongly adhering film" I can not remember much, unfortunately. The labels are about the adhesive force of an ordinary strip of adhesive tape.
Since they are a little wider and round, but you can reseal bulk goods very well. The closure keeps safe. But only until the next opening.
I had my bag of coffee beans resealed and stored in the closet. Reopening the adhesive closure went very easy, however, stuck the label a second time as well. So had to restore a new one.
My conclusion:. For single use in the household or for the sale of bulk goods such as loose tea, spices or similar. very suitable.
The labels are only limited reusable, however, temperature resistant (freezer or refrigerator) and easily labeled. Unfortunately, they are not labeled with inkjet printers, but only with laser printers.
