Hermetic seals for temporary use. These clips can be used instead of a heat sealer. The clip is designed to seal a flat bags with three heat sealed sides. It is important to use these clips only within room temperature range. It is difficult to obtain a perfect hermetic seal with them at extremely high temperatures. In addition, when the clips are used to seal a thin film bag after using it to seal a thick film bag, a complete seal may sometimes not be obtained.
After separating the interlocked parts of the clip, press evenly to close them over the mouth of a high barrier film bag. To remove the clip detach the two parts at one end and pull apart.
