包装

双层包装。内层为无毒PVC塑料袋，外层为瓦楞纸箱。

储存

1、因空心胶囊具有含水量过少容易碎裂、过多容易软化变形的特性，所以空心胶囊出厂的水份应控制在12.5–17.5%之间。

2、装有胶囊的容器应置放于货架上，避开窗户和管道使其处于阴凉通风处，避免日光照射和靠近热源。

3、不可随意放置和重压。

4、未使用前包装容器应保持密封，如果已打开请采取相应灭菌措施，否则易造成细菌污染。

5、库存温度应保持在15 - 25℃；相对湿度保持在35–65%。

6、不可储藏于高温高湿条件下，否则会因受热变软而发生粘连和变形，也不可置放于温度过低或过于干燥的环境下，否则胶囊易产生发脆易碎现象。

7、按上述储存条件储存，胶囊可完好地储存9个月以上。

运输

在运输过程中注意防压、防晒、防潮、防热。

英语简介

Introduction:

Empty (Vacant) capsule is one of the most common choices for medicine filling, and it has acquired an important position in the industry of medicine manufacture. Since the quality and material of the vacant capsules directly affects the effect and safety in medicine usage, our factory has always been searching for new and good material to improve the quality of the capsule shells, and try to make the best products to our customers.

The empty capsule is a kind of capsule shell with designated colors (prepared at the specific requirement of the customer) and shape made of gelatin as main material. It is usually used as the special packing for those medicines or health products with bad smell, light sensitiveness or labialisation in wet or hot conditions. No bond or additional pressure is required in producing capsules with vacant capsules. In addition, the specific capsules are easy to disintegrate in the gastric juice. Compared with tablets and pills, the capsules can offer a better bioavailability and other advantages in convenient preparation, carriage and usage and safe airproof packing.

Vegetable（cellulose） capsules（植物胶囊）, different from the traditional glutin capsules, are made of HPMC(hydroxy, propyl, methyl and cellulose) with the basic elements of polysaccharides and plant cell wall. In addition to its advantage in natural concept, it can also promote the absorption and digestion of albumen, fat and carbohydrate, which absent in the traditional glutin capsules. Along with the growing of vegetarianism and the sense of health protection, as well as the influence of the religion etc., the natural vegetable capsule products are rising to the leading position in its industry.

Vegetable capsule is made of HMPC by new technique, it’s a natural high-tech product.

Unlike gelatin capsules, vegetable capsules are made from natural plant cellulose in order to satisfy vegetarian and cultural lifestyle needs. While retaining all the advantages of traditional gelatin capsules, vegetable capsules also starch-free, gelatin-free and contains no preservatives. It does not need to be sterilized with ethyleneoxide.

HPMC(hydroxy, propyl, methyl and cellulose) is made of plant cellulose. It has been widely applied in food, cosmetics and pharmaceutics industries all over the world. HPMC used to produce veg-capsules meet USP/BP standard.

Veg-capsule can also be colored by natural edible colorants, and imprinted with natural printing inks to identify your products in the market. Besides, veg-capsules run smoothly on all kinds of hgh speed and semi-automatic filling machines.

The gastric coated capsules (胃溶胶囊) is a kind of capsule shell with designated colors (prepared at the specific requirement of the customer) and shape made of gelatin and gastric coating as main material. It is a capsule designed with specific target, it’s disintegrating quickly in the gastric juice. It's usually used in the packing of the medicines or health products with excitation to the stomach, labialisation in acid environment or specific requirement to disintegrate in the gastric juice to take effect. The specific gastric-oriented capsules help to promote the effect with a less dosage while reducing the adverse reaction, which is convenient for the patients. In addition, it helps to reduce the degradation to the medicine or health products caused by oral application and supply the best place for absorption.
