There are many materials for jewelry packaging boxes, commonly used ones are wood, plastic, paper, etc. Different materials are used for different grades of jewelry packaging. The plastic box is made of PVC/PET/PP/PS materials, etc., and can be made into different box types, as well as UV offset printing, silk screen printing, bronzing/silver, frosted, and other printing effects. As a jewelry box manufacturer, we can meet the different needs of different customers.
What are the advantages of jewelry packaging box plastic box material? The plastic box has the advantages of durability, moisture-proof and waterproof, high toughness, strong transportation safety performance, and improved product quality.
The plastic box is made of synthetic or natural polymer resin as the main material. After adding various additives, it has ductility under certain temperatures and pressure and can be shaped after cooling. The natural or synthetic polymer resin molecules are in a molten state, and the process in which the additive molecules are evenly distributed around is called plasticization. Plastic packaging is one of the four major materials in the packaging industry: 30% paper and cardboard, 25% plastic, 25% metal, and 15% glass.
Jewelry packaging box Plastic boxes are characterized by low density, lightweight, and easy processing. The appearance can be transparent or opaque.
1. It is easy to form, just need to replace the mold, you can get different varieties of containers, easy to start mass production.
2. The packaging effect is good, there are many varieties of printed plastic boxes, easy to color, and the color is bright. Different types of packaging containers can be made according to needs to obtain the best packaging effect.
3. It has good corrosion resistance, acid and alkali resistance, oil resistance, and impact resistance; and has good mechanical strength
According to the different uses of different materials, generally, jewelry packaging boxes have professional signs to distinguish them.
1-PET polyethylene terephthalate: Carcinogens produced after 10 months of use. This material has a very high probability of being thrown away after use and is usually used as a mineral water bottle, feeding bottle, etc. It is not suitable for supercooled and superheated water, and it is easy to precipitate the carcinogen DEHP.
2-HDPE (High-Density Polyethylene): Not easy to clean, easy to breed bacteria, and not recommended for repeated use. Usually, cosmetic bottles, shower gel plastic small package transfer bottles belong to this material.
3-PVC (polyvinyl chloride): It is easy to precipitate harmful substances in high temperatures and grease, and is often used in raincoats, plastic toys, building materials, etc.
4-LDPE (Low-Density Polyethylene): It is easy to produce harmful substances at high temperatures. Plastic bags and plastic wraps commonly used in daily life are all these materials. Wrapping food in plastic wrap and heating it is easy to dissolve harmful substances in the case of grease.
5-PP (Polypropylene): The only material that can be used for microwave heating, a very healthy material. It can be reused after careful cleaning, but generally, the lid of the plastic box of the microwave oven is not made of PP, so it is recommended to remove the lid when heating.
6-PS (polystyrene): heat-resistant and cold-resistant, it is the material for making noodle bowls and fast food boxes. Can't put it in the microwave, because the temperature is too high to produce chemicals, so we need to reduce the amount of hot food in fast food boxes.
7-AB (acrylonitrile butadiene): cannot be used for food packaging, but before 2008, code 7 mainly referred to all plastics except 1 to 6, and plastic milk bottles and water dispensers are usually marked as "7" plastics.
