Paper-plastic paper tray is currently a new type of packaging that is very environmentally friendly and suitable, so many categories of products are gradually beginning to use paper trays as packaging, and paper tray packaging usually needs to be customized based on its own products. The following mobile phone paper tray supplier Kasino will give you Share some common questions from customers who customize packaging paper trays!
1. Why can't the color I need be done or not done well?
In the dyeing of paper-plastic paper trays, most of the water-based dyes are used in the preparation process of the original pulp based on the pulp preparation process. First, the change of the slurry concentration with the consumption of the suspension also leads to the change of the dye concentration, and the second is that most dyes are very sensitive to temperature ( During the drying process, the color changes with the temperature of the drying line, and the temperature of the mold during hot pressing is 150°～250°, and the dye will also change at different temperatures). In summary, products with higher color requirements should not be dyed.
2. Why are there slight cracks on the appearance of this product?
When the paper-plastic paper tray is formed, the pulp fibers are naturally adsorbed layer by layer, and the liquid pulp will not flow out in some grooves, which will cause the thickness of the paper tray to be monotonous in different positions and the thickness of the design specification. Error, then when receiving a strong external force during high-pressure shaping, the fibers will break from the uneven thickness of the inner and outer layers to the outer layer, which will appear as micro cracks from the outside. This phenomenon will not affect the strength of the paper tray packaging, so it is acceptable in the industry.
3. Why can't I add a buckle to buckle my product?
The paper-plastic paper tray is closed up and down during molding and shaping, and must have a certain draft angle. The wet product cannot be removed from the mold during molding, so the paper tray cannot be designed with an inverted position.
4. Why is there a big difference in the hardness of different paper trays?
The basic anti-vibration buffer principle of the mobile phone paper holder is completed by the application of loop structure and reinforced ribs. Therefore, different designs and structures of the same slurry will have different anti-vibration strengths, and the texture will be different when touched. The same model molds use different pulps. Material, due to the difference in the length of the pulp fiber and the shrinkage characteristics, the texture will be different on the hand. Therefore, before selecting materials and design plans, we must let the engineer know the required seismic specifications, so that we can design different loop structures and reinforcement ribs in accordance with the seismic requirements during the design.
5. Why are there uneven rough edges around the flanging mobile phone paper holder products?
The flanging structure product is formed with a flat edge. The edge of the mold is a stainless steel filter when the vacuum is formed to absorb the pulp naturally. After the pulp fiber is adsorbed, the edge will be irregular cotton wool. This is formed by the uncontrollable process. The back edge will be turned to the side without affecting the packaging, and the industry is not used as a consumption control element. Assuming that the customer has very high requirements for this, trimming can be used, and the burrs can be cut off with a knife.
