End Users Have A Few Requirements For Cosmetic Packaging

May 06, 2018

Cosmetic packaging bottles are more complex, including the first, second or third layer packaging and outer packing. First layer packaging category, including bottle classes (such as plastic bottle and glass bottle), hose (such as plastic hose, metal hose, composite hoses), bags, such as paper bags, plastic bag, compound bag, etc.; The packaging category of the second or third floor includes boxes (such as carton, plastic box, metal box), label class, plastic suction class, etc. The outer packing includes buffer packing and so on.

The appearance requirements of different levels of packaging have commonness and inherent particularity. The commonality of appearance requirement includes the packing printing pattern and the handwriting should be neat, clear, not easy to fall off, the color should be uniform and so on. The particularity of appearance requirement varies according to the packaging of different categories.

For bottle packing, the bottle should be smooth, smooth and uniform, without obvious scars and deformation, and should not be cold and cracked. The mouth of the bottle should be straight, smooth and should not have burr (muzzle). The structure of thread and bayonet should be intact and correct. The combination of bottle and lid should be tight, without sliding teeth, looseness and leakage; The inside and outside of the bottle should be kept clean.

For bag packaging, it should not have obvious wrinkles, scratches, air bubbles, the color should be uniform; Seal should be firm, should not have openings, perforation, leakage (paste) phenomenon; The composite bag should be strong, and the coating layer is uniform and non-shedding.

Material requirements.

In order to achieve sustainable development of packaging, biodegradable materials have emerged and become a hot topic in the industry. Biological degradable material is refers to the use of renewable materials, such as crops, trees and other plants and residue and inclusions as raw material, through the biological, chemical and physical methods such as made of a class of new materials.

Products made from biodegradable materials are usually green, environmentally friendly, renewable and biodegradable.

Currently, large companies such as dupont and basf of Germany are actively expanding their bio-based chemicals business. A packaging development worker as cosmetics production enterprise, the author hope that the future can be biological degradable material used in the cosmetics packaging, promote the sustainable development of cosmetics bottles.

Structural design requirements

For cosmetics, the first layer of packaging is very important, directly related to product quality. The first layer of cosmetics is mostly plastic containers, and the structural design of plastic containers can not be separated from the selection of materials and molding process. The commonly used plastic materials can be divided into soft materials and hard materials, which are typical soft materials represented by PE and PP, and typical hard materials represented by ABS and PMMA.

Plastic containers are commonly used in molding process, such as injection molding, hollow molding, injection molding, etc. However, no matter which molding process is chosen, the sealing design and capacity design of plastic containers are of great importance.
