Description

Sandwich packaging bag with three-dimensional partition structure

This creation is about a sandwich-type packaging bag with a three-dimensional partition structure, especially And a three-dimensional separation structure, especially a sandwich-type packaging bag that can be used to separate cake slices and fillings with different ingredients and characteristics to prevent the filling moisture from softening the cake slices during storage and affecting the taste or flavor characteristics during use.

Many foods often use sandwich or sandwich structures to create different tastes and flavors of the food. Taste, such as: sandwiches, burgers and sandwich biscuits, etc. Since sandwiches and burgers are eaten fresh, fillings such as ham, hamburger, lettuce and eggs are prone to bacteria at room temperature, and refrigeration will accelerate the aging of bread starch. Therefore, the shelf life is short and has its limitations; as for sandwich biscuits, the water activity of biscuit and cream sandwich is lower than 0.6, so under appropriate packaging, it can be stored at room temperature for at least 3 to 6 months. Refrigeration will not cause starch to age. They are crispy and delicious, and the sandwich is rich in oil and grease. Many flavor substances are often added, so they are widely loved by consumers. However, sandwich biscuits are high in calories, and their ingredients are mostly starch, saturated fats and oils. Sugar, etc., lack dietary fiber, protein, vitamins and minerals, etc., which often do not meet the health needs of modern consumers. Commercially-available rice balls or hand rolls use ingenious packaging design to separate the dry and crisp seaweed from the rice balls or fillings in advance. When consumers want to enjoy it, they only need to tear open the pre-prepared tear strips of the packaging. By threading the line, the separation part can be pulled away, so that the seaweed is in contact with the rice balls or fillings, so that consumers can enjoy the crispness of the seaweed, the softness of the rice balls, or the fresh taste and flavor of the fillings. However, its design is only suitable for ingredients with a 2D planar structure, such as paper-thin seaweed, but is not suitable for cakes with a certain thickness, such as 3D biscuits with different thicknesses or irregular shapes. If rice crackers are used reluctantly and the inner layers are overlapped rather than sealed, the irregularly shaped cake pieces are more likely to dent the overlapping inner layers, resulting in poor sealing and unable to fully achieve the effect of dry and wet separation. And its application is greatly reduced. In view of this, it is necessary to develop an invention that can solve the packaging problems of 3D food ingredients and the shortcomings of previous technologies.

The main purpose of this creation is to overcome the above-mentioned problems encountered in traditional knowledge and skills and provide The invention provides a sandwich-type packaging bag with a three-dimensional separation structure that can be used to separate cake slices and fillings with different ingredients and characteristics to avoid filling moisture from softening the cake slices during storage and affecting the taste or flavor characteristics during use.
