Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Example 1: the embodiment of the application discloses resistant high separation wrapping bag that cooks, as shown in fig. 1 and fig. 2, including first diaphragm 1 and second diaphragm 2, the equal fixedly connected with polyester film layer 11 in one side that first diaphragm 1 and second diaphragm 2 kept away from each other, the equal fixedly connected with nylon layer 12 in one side that first diaphragm 1 and second diaphragm 2 are close to each other, first diaphragm 1 and second diaphragm 2 are sealed through the heat-seal of hot cutter all around. First diaphragm 1 and second diaphragm 2 all around equal fixedly connected with leak protection strip 13, leak protection strip 13 is the same with 11 materials of polyester film layer, and leak protection strip 13 can wrap up the border setting all around of first diaphragm 1 and second diaphragm 2. Leak protection strip 13 is close to first diaphragm 1 and 2 one side fixedly connected with glue film 131 of second diaphragm, and glue film 131 can make leak protection strip 13 and first diaphragm 1 and 2 bonding of second diaphragm inseparable, prevents to take place the bag that expands in the high temperature steaming and boiling in-process, takes place the damage with first diaphragm 1 and 2 junctions of second diaphragm, makes the steam of the in-process of cooking enter into in the bag or the bag product spills the bag body.

As shown in fig. 1 and fig. 2, an easy-to-tear line 14 is embedded at a position corresponding to the leakage-proof strip 13 on one side of the first membrane 1, the easy-to-tear line 14 is arranged at a position between the first membrane 1 and the second membrane 2, an easy-to-tear opening 15 is formed at a position corresponding to one end of the easy-to-tear line 13, the easy-to-tear line 14 is fixedly connected with a thickening sheet 141 corresponding to the position of the easy-to-tear opening 15, an indent 16 is formed at a position corresponding to one side of the easy-to-tear line 14 on the polyester film layer 11, and the indent 16 is pressed out by a hot press.

The implementation principle of this application embodiment 1 resistant high separation wrapping bag that cooks is: in the use process, a user can tear the easy-to-tear line 14, so that the easy-to-tear line 14 is torn along the length direction of the dent 16, the leakage-proof strip 13 and the second membrane 2 are torn, and finally the user can take out the articles in the bag conveniently. Simultaneously in the high temperature steaming and boiling in-process, leak protection strip 13 can make first diaphragm 1, second diaphragm 2 when the bag phenomenon that expands takes place at the steaming and boiling in-process, and leak protection strip 13 can prevent that first diaphragm 1 and 2 junctions of second diaphragm from taking place to separate, causes the wrapping bag damaged at last, and article spill in the bag.

Example 2: as shown in fig. 1 and 3, the thickness of the leakage-proof strip 13 is set to be 3 times of that of the first membrane 1 and the second membrane 2, the first membrane 1 and the second membrane 2 are made of aluminum foil, and the two polyester film layers 11 are fixedly connected with the nano-alumina coating 3 on the side close to each other.

The implementation principle of this application embodiment 2 a resistant high separation wrapping bag that cooks is: the user is in the use, and leak protection strip 13 can be more convenient for the user to grip the wrapping bag after heating, after picking up the wrapping bag, because the outstanding first diaphragm 1 of leak protection strip 13 and the surface of second diaphragm 2, can prevent finger and the bag body direct contact of wrapping bag when the user picks up, causes the hand to be scalded, and nanometer aluminium oxide coating 3 can prevent that the food in the wrapping bag is depositing the in-process at ordinary times and is shone rotten by ultraviolet irradiation.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
