The selection of packaging materials is very important. Although the factors that the manufacturers of perforated fruit bags need to consider are different, they are also similar. They should pay attention to the following properties:
1、 Excellent protection performance.
Protection performance mainly refers to the protection of the contents, to prevent their deterioration and to ensure the quality. In the selection of packaging materials, attention should be paid to the mechanical strength, moisture and water absorption, corrosion resistance, heat and cold resistance, light transmittance, air permeability, UV penetration resistance, oil resistance, temperature variability, non-toxic, no odor and other performance indicators.
Take sucking jelly bag as an example.
1. No leakage or leakage is allowed in the long-term storage of suction jelly bag. The heat sealing material of the composite packaging bag must have good low temperature heat sealing performance and heat sealing strength (heat sealing temperature ≤ 135 ℃, heat sealing strength of PET composite product ≥ 50N / 15mm, and that of NY composite product ≥ 60N / 15mm).
2. The materials used for sucking jelly bags must be non-toxic, odorless, tasteless, stable in chemical properties, and can not react with the contents. The manufacturers of perforated fruit bags should strictly control the residual amount of solvent in the production process, which must meet the national standards. The composite bag must be safe. No accidental injury or ingestion is allowed.
3. Liquid jelly in the filling, packaging, transportation, sales, consumption process will inevitably have the phenomenon of extrusion, pile up, drop, which requires that the composite packaging bag must have excellent compression performance and impact resistance, to prevent damage, at this time the mechanical strength of packaging materials is very important.
2、 Processing performance.
Processing performance mainly refers to easy processing, easy packaging, easy filling, easy sealing, and suitable for automatic packaging machine operation. In the selection of packaging materials, attention should be paid to the strength, flexibility, wear resistance, water resistance, thermal sealing and anti-static performance of packaging materials.
3、 Appearance decoration performance.
Appearance decoration performance mainly refers to the beauty of the shape, color and texture of materials, which can improve the value of goods and stimulate consumers' desire to buy. In the selection of packaging materials, attention should be paid to the transparency, surface gloss and other performance indicators of packaging materials.
4、 Easy to handle performance.
Easy to handle performance mainly refers to the packaging materials to be conducive to environmental protection, to save resources. In the selection of perforated fruit bag materials, attention should be paid to the recyclable, recyclable or renewable packaging materials. http://www.ycritai.cn/
