The sealing of the Pastry Blister Packaging Box is crucial to keep the freshness and taste of the pastry and prevent it from getting damp. Here are some effective ways to ensure its sealing.
First of all, the choice of materials is the key. High-quality blister materials should have good flexibility and barrier properties. For example, the selection of plastic materials with higher density and lower air permeability can effectively prevent moisture in the air from entering the interior of the packaging box.
During the production process, the precision of the mold and the control of the process play an important role in the sealing. The design of the mold should ensure that the edges and seals of the packaging box fit tightly without gaps or gaps. The process parameters of blister molding, such as temperature, pressure and time, need to be precisely controlled to ensure that the shape and size of the packaging box are accurate, the seal is flat and smooth, and the sealing effect is improved.
The structural design of the packaging box can also affect the sealing. Reasonable design of the sealing form, such as heat sealing, high-frequency sealing or ultrasonic sealing, can enhance the strength and sealing of the seal. At the same time, a sealing strip or sealing coating can be added to the seal to further improve the moisture-proof performance.
In addition, the operating specifications during the packaging process should not be ignored. Ensure that the pastry will not cause damage or contamination to the seal when it is placed in the packaging box. During the sealing operation, ensure that the temperature and pressure of the seal are uniform, the sealing time is sufficient, and the seal is firm and tight.
For mass-produced Pastry Blister Packaging Box, quality inspection is an indispensable link. Through random inspection, the packaging box is tested for sealing, such as vacuum test, pressure test or water immersion test, etc., to promptly find and remove packaging boxes with sealing defects.
During storage and transportation, attention should also be paid to the impact of environmental conditions on sealing. Avoid exposing the packaging box to high temperature, high humidity or corrosive substances to avoid affecting the performance of the material and the sealing effect of the seal.
In summary, to ensure the sealing of the Pastry Blister Packaging Box and prevent the pastry from getting damp, it is necessary to comprehensively consider and strictly control multiple aspects such as material selection, production process, structural design, operating specifications, quality inspection, storage and transportation.
