1. The performance of the packaged product
The performance of the packaged product in a packaging printing plant mainly includes the physical state, shape, strength, weight, structure, value, and risk of the product. This is the first issue that should be considered when packaging.
①The physical state of the product in the packaging and printing plant. There are mainly solid, liquid, gaseous, mixed, etc. The packaging containers are also different for different physical states.
② Product appearance. There are mainly square, cylindrical, polygonal, special-shaped, etc. The packaging should be designed according to the appearance characteristics of the product, and the packaging should be small in size, well fixed, stable in storage, and meet standardization requirements.
③Product strength. For products with low strength and susceptibility to damage, the protective performance of the package should be fully considered, and there should be a clear mark on the outside of the package.
④ Product weight. For heavy products, pay special attention to the strength of the packaging to ensure that they are not damaged in circulation.
⑤ Product structure. Different products often have different structures, some are not pressure resistant, and some are afraid of impact. Only by fully understanding the structure of the product can we properly package different products.
⑥ Product value. Different products have great differences in value, and the highest value should be considered.
⑦The product is dangerous. For flammable, explosive, toxic and other dangerous products, to ensure safety, there should be precautions and specific marks on the outside of the package.
2. The impact of the environment on the product
In the process of circulation, products will encounter different environments, which will have different effects on packaging, so corresponding measures should be taken.
① Meteorological conditions. Mainly include sunlight, temperature, humidity, rain, snow, and air. They have different effects on different products, which need to be considered separately for different meteorological conditions.
② Loading and unloading conditions. Should consider whether it is manual or mechanical loading and unloading, as well as conditions such as the number of loading and unloading.
③Transportation conditions. During transportation, products are subject to impacts, vibrations, etc., and different transportation vehicles have different effects on packaging. Mainly should consider product fixation and cushioning.
④Storage conditions. Stacking is used for storage, and its compressive strength should be examined for packaging. In addition, storage is divided into indoor storage and outdoor storage. The former should be protected from moisture, mildew, and water; the latter should be protected from rain, snow, sunlight, and wind.
3. Choice of packaging method
The choice of packaging method is very important for product protection. Only by understanding product performance and circulation conditions, formulating several schemes, and conducting economic evaluations can a suitable packaging method be found.
①Choose packaging materials. Choose suitable packaging materials to make packaging containers according to product performance, and choose appropriate accessory packaging materials to package products.
②Choose the packaging method. According to the requirements of product protection strength, easy to use, convenient for mechanical loading and unloading and transportation, choose the appropriate packaging technology and packaging method.
