The hem seal 7 is formed so that the hem seal becomes part of the bag and is not visible from the appearance, giving a more aesthetically pleasing appearance. When the mixed invisible edge sealing bag is wrapped with one vacuum heat insulation plate, two side faces of the vacuum heat insulation plate representing the thickness are respectively wrapped by two transparent films 6, two side faces of the vacuum heat insulation plate representing the heat insulation are respectively faced to two aluminum foil films 5, so that two sides of the vacuum heat insulation plate representing the thickness are only wrapped by the transparent films 6, and the heat loss possibility is greatly reduced when the transparent films 6 are attached to the vacuum heat insulation plate due to the fact that the heat conductivity of the transparent films 6 is low, so that the heat loss is reduced, the edge heat bridge effect is effectively reduced, and the comprehensive heat insulation performance of the vacuum heat insulation plate is further improved. Compared with embodiment 3, the amount of the transparent film 6 is reduced, and the manufacturing cost is reduced.
Example 5
The embodiment also discloses an invisible edge sealing packaging bag applied to the vacuum heat insulation plate, which comprises two aluminum foil films 5 and two aluminum-plated films, wherein one ends of the two aluminum foil films 5 are respectively in hot-pressing lap sealing with two ends of one of the aluminum-plated films, the other opposite ends of the two aluminum foil films 5 are respectively in hot-pressing lap sealing with two ends of the other one of the aluminum-plated films, and a mixed invisible edge sealing bag is enclosed by the aluminum-plated films-aluminum foil films 5-aluminum-plated films-aluminum foil films 5 in sequence. The hem seal 7 is formed so that the hem seal becomes part of the bag and is not visible from the appearance, giving a more aesthetically pleasing appearance. When the mixed invisible edge sealing bag is wrapped with one vacuum heat insulation plate, two sides of the vacuum heat insulation plate representing the thickness are wrapped by two aluminum-plated films respectively, two sides of the vacuum heat insulation plate representing the heat insulation face the two aluminum foil films 5 respectively, so that two sides of the vacuum heat insulation plate representing the thickness are wrapped by the aluminum-plated films only, and the possibility of heat loss is greatly reduced when the aluminum-plated films are attached to the vacuum heat insulation plate due to the fact that the thermal conductivity of the aluminum-plated films is low, heat loss is reduced, the edge heat bridge effect is effectively reduced, and the comprehensive heat insulation performance of the vacuum heat insulation plate is further improved. Compared with the embodiment 2, the dosage of the aluminum plating film is reduced, thereby reducing the manufacturing cost.
The service life of the VIP panels of the invisible edge sealing packaging bag in this embodiment, the traditional VIP panels of the aluminum-plated bag with three-side sealing and the transparent bag with three-side sealing were tested, the test standards and test conditions were the same as those in embodiment 1, and the test results are shown in table 3:
age-related comparison test data
VIP packaging form λ0 λ1 λ2 λ3 λ4 λ5 λ6 λ7
Three-side sealed aluminum-plated bag VIP 2.01 1.95 2.33 2.98 3.37 3.8 4.32 4.89
Three-side sealed transparent bag VIP 1.93 2.76 3.1 3.67 3.62 4.01 4.45 5.2
Invisible edge sealing packaging bag VIP 1.72 1.71 1.88 2.03 2.28 2.4 2.79 3.31
And (4) conclusion: the performance of the VIP plate manufactured by adopting the invisible edge sealing packaging bag is far better than that of a VIP plate manufactured by a three-edge sealing aluminum-plated bag or a non-aluminum bag in the aspect of life aging test. Meanwhile, the comprehensive heat transfer coefficient of the invisible edge sealing is equivalent to that of a VIP plate made of a double-sided aluminum-plated bag or a non-aluminum bag in the aspect of testing. Therefore, the invention of the invisible edge sealing packaging bag not only enables the VIP board to obtain excellent aging life, but also improves the heat preservation and heat insulation performance (namely lower heat transfer coefficient) of the whole VIP board, and simultaneously the product has beautiful appearance, and the cost is greatly reduced by adopting less transparent films or aluminized films.
The heat transfer coefficient test was conducted on the vacuum insulation panels packed in the packing bags manufactured in examples 1 to 5 of the present invention, and the heat transfer coefficient test was conducted on the vacuum insulation panels packed in the packing bags of the present invention using 300mm (width) 300mm (length) 10mm (thickness) as samples, and the results are shown in Table 4
TABLE 4 comprehensive Heat transfer coefficient data comparison table
Figure BDA0002354055690000111
As can be seen from the above table, the overall heat transfer coefficient including edge seal heat conduction is relatively low, substantially 0.2 w/(m)2K), so that the same heat transfer coefficient requires higher material cost by adopting the traditional edge sealing technology, and the packaging bag prepared by the invention can improve the comprehensive heat-insulating property and save the cost.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
