Design skills of grain packaging bag appearance

In the grain packaging and sales industry, we all know the importance of design for a product. Good design can add charm to the product and increase sales. How to design good packaging bags is a difficult problem faced by many people. Next, let's take a look at the factors that have a great impact on the packaging design of grain packaging bags.

1) Determine the shelf life requirements of products, and determine the packaging benchmark according to the characteristics of products and the shelf life required in the market.

2) Investigate the sales situation, investigate the display status and storage status of products similar to the products we plan to produce in the market, so as to determine the sales method and sales location.

3) Determine the product specifications, and specify the specifications of packaged products, such as the weight, volume, quantity, coloring, organizational form and packaging cost of packaged products.

4) Determine the packaging form based on the market requirements and with reference to the strength and toughness of the products required by the seller.

5) The safety of packaging materials should be checked to ensure the safety of food.

6) Determine the type of packaging machine and determine the type of packaging machine according to different packaging methods.

① The determination of manual and automatic packaging machines depends on the study of thermal adhesion and formability of packaging materials.

② The determination of intermittent and continuous packaging machines depends on the research of thermal adhesion, formability, sliding, spacing stability, anti electrification and anti deformation of packaging materials.

7) When determining the packaging materials of grain bags, the appropriate film can be selected while determining the packaging machine. In addition, the performance of packaging materials can be determined according to the circulation status and sales display effect.

① In terms of circulation, it has impact resistance, cold resistance and thermal adhesion.

② In terms of display, gloss, transparency, printability, deformation resistance and shading.

③ In terms of products, air barrier, oil resistance and moisture resistance.

④ In terms of cost, the film thickness and packaging size of the selected packaging materials shall be considered, and the cost shall be set within 10% of the retail price.

8) Determine the packaging method. Determine the packaging method according to the packaging benchmark and packaging form. When packing tightly, check the gas barrier according to the degassing mode and vacuum mode. To study the impact resistance, the heat resistance and thermal shrinkage should be studied according to whether secondary sterilization is carried out; When packaging with air, we should study the air barrier, oil resistance and thermal adhesion.
