Appearance requirements of health food packaging

because various functional components or symbolic components of health food are easily affected by air, temperature, humidity, light, microorganisms and other factors during storage, various complex physical, chemical or biochemical changes will occur, which will further affect the quality and use safety of health food, Therefore, the selection of appropriate packaging materials and advanced packaging technology are closely related to the quality of health food. The main function of health food packaging is to protect the quality of health food and prevent the failure and deterioration of functional components or symbolic components of health food

protect the functional components or iconic components of health food

regardless of the state of its dosage form, health food is generally prone to oxidation and bacteria infection in the air, decomposition and discoloration in the light, deliquescence and deterioration in the moisture, volatilization, softening, melting and disintegration in the heat, deformation, fragmentation and other problems caused by intense vibration. Changes in the physical or chemical properties of health food will invalidate the functional components or landmark components, which will not play a role in health care, and some will cause disease instead. Moreover, most health food has a factory shelf life of about two to three years. In such a long time, entering gas and water through the pores of the container wall (such as polyethylene, polypropylene and other plastics) or the gap between the container and the cover (not tightly sealed or deformed) will lead to the deterioration of health food. Within the warranty period, the manufacturer shall bear the problems existing in the preservation of health food. Therefore, the protection function is very important for manufacturers and consumers. No matter in the design of shape, structure and decoration, or in the selection of materials, the protection function should be considered as the primary factor, and in all aspects of the protection function (such as shockproof, cold proof, heat proof, radiation proof, insect proof, etc.), sealing, that is, complete isolation from the outside world, is the most important

1 "a stall owner answered Barrier effect

the packaging should make the drug components in the container can not penetrate and escape, and the external air, light, moisture, heat, foreign bodies, microorganisms... Should not enter the container to contact with the drug. The stability and efficacy of many health foods will change with the gas, light, heat, moisture... Entering or escaping from their packaging containers. For example, tablets, Oriental film metropolis, China Railway Qingdao World Expo City and more than 30 large projects with a value of 10 billion yuan have been accelerated, and solid preparations such as granules have become moldy and deteriorated due to the moisture of such casually burned cores; Liquid health food such as oral liquid is fermented by temperature, light, air and microorganisms. In terms of barrier effect, the following aspects should be highlighted:

(1) anti penetration: volatile functional components or iconic components can be dissolved in the inner side of the packaging material, and diffuse and move to the other side by means of osmotic pressure. That is, volatilization can be diffused from molecules on the container wall. You can smell the medicine obviously from the outside of the package. In particular, paper packaging, polyethylene single-layer plastic film and other packaging have obvious permeability, light transmission and water permeability. Not only do aromatic components of drugs escape from the wall, but gases (such as O2, CO2) and steam can directly enter the container through the packaging materials, affecting the stability of health food. Such as vanilla oil, it has a strong corrosion effect on general organic packaging materials, and its penetrability is more obvious. It penetrates out in less than two weeks in the hard capsule shell made of gelatin. In order to prevent penetration, materials with low permeability should be selected as a single package of drugs when selecting packaging materials. In this respect, all kinds of composite membrane containers, glass containers, metal containers and ceramic containers have good effects

(2) leakage prevention: volatile or nonvolatile components of health food, solid or liquid drugs escape or leak through discontinuities or packaging materials, such as pinholes, cracks on materials or gaps between covers and containers. This kind of situation mostly occurs in the case of improper structural design and packaging technology of packaging containers. Of course, sometimes it is also caused by improper material selection

(3) shading: vitamin E and other functional components oxidize and deteriorate when exposed to light, and coated pills and tablets (especially lemon yellow colored clothes) darken due to light. In addition to sealing, the packaging of this kind of health food also needs to be shading. Three methods are often used for shading of health food packaging: ① traditionally, brown bottles are often used or the contents in the bottles are wrapped with paper; ② The new material is aluminum plastic film, aluminum, paper plastic composite film; ③ Add sunscreen in packaging materials, such as titanium dioxide

3. Buffer effect

during transportation and storage, health food will be subject to vibration, impact and extrusion of various external forces, which is easy to cause damage. For example, the glass bottle packaging is easy to crack; Packaging such as film and paper bag is easy to deform. Therefore, health food packaging should have a cushioning effect to prevent vibration, impact and extrusion

(1) function of gasket: Gaskets should be used inside and outside a single package. It is an important part of the sealing device and a favorable measure to prevent vibration. Pills, tablets and other solid drugs are often filled with sterile cotton, paper strips or plastic spring rings on the plastic cover in the excess space of the container, so that the drugs will not move when the bottle is full of cold. The outside of a single package (that is, the container) uses corrugated paper or hard plastic to make corrugated groove plates to fix and separate each container. At present, new materials such as foamed polyethylene, foam polypropylene, polyethylene and polystyrene copolymer resin foam are used as buffer packaging, and the effect is good

(2) outer packaging is also called distribution packaging: it is a large container made of materials with certain mechanical strength, which has the functions of shock resistance, pressure resistance and sealing

international transportation packaging: in addition to general requirements, the following items should be tested for complete and full transportation packaging:

① mark the position and firmness of the packaging; ② Regulating performance of temperature and humidity; ③ Stacking experiment; ④ Vertical impact test by falling; ⑤ Horizontal collision test, inclined plane test, swing test, etc

4. The surface of other

packaging materials cannot have any effect in the long-term contact with health food, and there cannot be any effect between its release and health food, or between the functional components or symbolic components released by health food and packaging materials

in addition, various additives (such as plasticizers, lubricants, release agents, stabilizers, antioxidants, antistatic agents, pigments, etc.) contained in packaging materials such as degradation products of plastics, coatings, plastics, rubber and other materials will also have anti radiation and heat insulation functions if released gradually during storage, polluting health food, which must be carefully considered
