Cosmetic packaging is more complex, including first-layer packaging, two- or three-layer packaging, and outer shipping packaging. There are many types of packaging on the first layer, including bottles (such as plastic bottles, glass bottles), hoses (such as plastic hoses, composite hoses, metal hoses), bags (such as paper bags, plastic bags, composite bags), etc. ; Second or third-tier packaging categories include boxes (such as cartons, plastic boxes, metal boxes), labels, blister, etc .; outer transport packaging includes buffer packaging.
The appearance of different levels of packaging requires commonality and also has its own inherent peculiarities. The commonality of appearance requirements includes that the package printing pattern and handwriting should be neat, clear, not easy to fall off, and the color and luster should be uniform. The particularity of appearance requirements varies according to different types of packaging.
For bottle packaging, the bottle body should be smooth, smooth, uniform thickness, no obvious scars and deformation, no cold burst and cracks; the bottle mouth should be straight, smooth, no burrs (threads), thread, bayonet The mating structure should be intact and straight; the cooperation between the bottle and the cap should be tight, without slipping, loosening and leakage; the inside and outside of the bottle should be kept clean.
For bag packaging, there should be no obvious wrinkles, scratches, air bubbles, and uniform color; the seal should be firm, and there should be no openings, perforations, and leakage (paste); the composite bag should be firm and composite, and coated Even and no shedding.
In order to achieve sustainable development of packaging, bio-based degradable materials came into being, and gradually became a hot topic in the industry. Bio-based degradable materials refer to a new class of materials made from renewable materials, such as crops, trees, other plants and their residues and inclusions, through biological, chemical and physical methods.
Products made from bio-based degradable materials are typically green, environmentally friendly, renewable raw materials, and first-grade biodegradable.
Currently, large companies such as DuPont in the United States and BASF in Germany are actively expanding their bio-based chemical business. As a packaging developer for a cosmetics manufacturer, the author hopes that bio-based degradable materials can be used in cosmetic packaging in the future to promote the sustainable development of cosmetic packaging.
2. Structural design requirements
For cosmetics, the first layer of packaging is very important and directly related to product quality. The first-layer packaging of cosmetics is mostly plastic containers. The structural design of plastic containers is inseparable from the choice of materials and molding processes. Commonly used plastic materials can be divided into two categories: soft materials and hard materials, that is, typical soft materials such as PE and PP and typical rigid materials such as ABS and PMMA.
Common molding processes for plastic containers include injection molding, hollow molding, injection blow molding, etc., but no matter which molding process is selected, the sealing design and capacity design of plastic containers are very important.
3. Seal design
Product sealing is a mandatory quality standard in the cosmetics industry. Generally, gasket sealing and quality (gross weight), volume, production date and shelf life or production batch number and deadline for use are selected, and GB / T191-2008 "Packaging, storage and transportation" is selected. The pictorial signs in Graphical Signs should be clear, complete, and appropriately positioned.
