Two-piece can manufacturer: packaging design of easy-to-open-lid cans

The two-piece can manufacturers tell you that the packaging design of cans of food is not only a means to enhance customers' desire to buy, but also a manifestation of brand culture. Unique packaging is not only a symbol of the brand, but also a silent spokesperson for the product. It not only promotes products and brands, but also affects consumers' desire to buy.

Two-piece can manufacturer: packaging design

When designing the shape of food packaging, consumers and products will be considered. From the perspective of consumers, packaging design on the market now tends to be convenient, such as easy to carry and easy to start with. Therefore, flexible packaging design and diversified The size design has become one of the mainstream trends in packaging design. Considering products, packaging design generally starts from the characteristics of raw material sources and product functions.


Two-piece can manufacturers: packaging color matching

Rich packaging colors show different quality styles and decorative charm. The choice and combination of colors is very important in packaging design. It is often the key to determine the quality of packaging design. Combining modern packaging design theory with the attribute requirements of commodities, canned food is packed with colorless gold, silver, black, white and gray, showing the eternal beauty of commodities.

Two-piece can manufacturers: factors affecting the vacuum degree of easy-to-open cans

There are many factors that affect the vacuum degree of the easy-to-open can, such as the exhaust sealing temperature, food freshness, food acidity, air volume in the food organization, canning conditions, top gap size, exhaust method, etc.

1. The top gap of canned food is often higher in vacuum degree when heating and exhausting, but the filling volume will be affected when the top gap is too large. When the top gap is vacuum sealed, the vacuum degree of the tank with small top gap in the tank is also low. When the top gap is small, the depression degree of the tank cover caused by the pressure difference between the inside and outside of the tank increases the influence on the top gap volume in the tank. If the tank is too tight, there would be no air space, and the vacuum would disappear.

2. The sealing temperature of the can, when heating and exhausting, the higher the sealing temperature, the higher the vacuum degree of the can after sealing. When the vacuum is sealed, the vacuum degree of the tank depends on the vacuum degree of the working room of the vacuum sealing machine, the pumping time and the sealing temperature of the tank.

3. The type and acidity of food raw materials. Different types and varieties of raw materials have different amounts of gas in their tissues. The higher the acidity of food, the more likely it is to cause acid corrosion and produce hydrogen, thereby reducing the vacuum of canned food.

4. The freshness and sterilization temperature of food raw materials. Raw materials with poor freshness will decompose to produce gas when they are heated for sterilization. The worse the freshness, the higher the sterilization temperature, the more gas produced and the lower the vacuum degree.

5. Temperature, as the temperature increases, the pressure of water vapor and residual air in the tank will increase, but the change in atmospheric pressure is generally small. Vacuum = atmospheric pressure-residual pressure in the tank. Obviously, the vacuum in the tank will increase with The temperature decreases, so for the same can, the vacuum in different regions or seasons is different.

6. Atmospheric pressure and altitude. According to the concept of vacuum degree, atmospheric pressure and altitude also have a great influence on vacuum degree. The higher the altitude, the lower the atmospheric pressure, and the lower the vacuum degree of the can.
