Analysis of the causes of burrs in the effervescent tube

 The effervescent tube is a special packaging for candy tablets such as effervescent tablets. It is composed of a bottle cap and a bottle barrel. Generally, injection molding technology is used in the processing method. However, burrs will appear during the production process. What is the cause?

There are many reasons for the burrs of the effervescent tube, which can be analyzed from the following aspects:

1. The clamping force is too low

Compared with the projected area of the molded part, if the clamping force is small, there will be a gap between the movable mold and the static mold due to the injection pressure, which inevitably produces burrs. Especially when the side gate is placed on the hole close to the center of the p art, since the molding gate requires a large injection pressure, it is very easy to produce burrs.

2. Deformation of the injection mold

If the originality of the mold is insufficient, it will deviate due to the injection pressure. If there is a hole near the center, burrs will be generated around the hole. When using the center hole to open the side door, the hole and the perimeter of the runner will also be created. glitch. The burrs generated for this reason are caused by poor mold manufacturing and are therefore difficult to repair. Reinforcing the mold can reduce burrs.

3. Plastic fluidity is too good

Just because the fluidity of the plastic is too good, theoretically speaking, it is not the cause of the burr. However, when the fluidity of the plastic is too good, even a small gap may be penetrated by the plastic, so burrs are prone to appear. In order to eliminate such burrs, the melting temperature or injection pressure can be reduced, and the mold temperature or injection speed can also be reduced.

4. There are foreign bodies on the surface of the injection mold

Foreign matter on the clamping surface of the mold will inevitably produce burrs. In order to solve this problem, it is obvious that the surface of the mold must be cleaned to close the clamping surface.

Burrs in the effervescent tube can be analyzed from the above aspects to find out the specific reasons to ensure the quality of the finished product.

The importance of effervescent packaging

 The main design of the effervescent tablet tube is the packaging of the effervescent tablet, which is moisture-proof and anti-damage. When the effervescent tablet is packaged early, it is the most prominent dryness of the package. There is a spiral spring to prevent the effervescence from being damaged during transportation.

Precautions for the production and packaging of effervescent tablets:

1. Do not make the acid and alkali together with the main drug during granulation, because the general acid or alkali will affect the stability of the drug and may lead to unqualified degradation products.

2. The disintegration degree is not more than 5 minutes according to the pharmacopoeia, which is relatively easy to achieve. Our internal control standard is 90 seconds. When granulating, use a binder with a low viscosity and use a high concentration of ethanol to granulate (such as absolute ethanol), so that it dries quickly, the particles are relatively loose, and the degree of disintegration is easily qualified. But pay attention to the friability, the pharmacopoeia stipulates no more than 1%. (But it seems that a special application can be made for effervescent tablets, which should be relaxed appropriately.) Finally, acid and alkali are added as additional auxiliary materials in the final mixing.

3. Be careful not to store the prepared pellets for too long, and control the humidity.

4. The humidity should also be controlled during tablet pressing to prevent water absorption.

5. As for packaging, you can choose double aluminum packaging or high-density polyethylene bottle or PP plastic bottle packaging that is not easily permeable to water and oxygen to ensure its stability.

How Can Plastic Vitamin Tube Keep Dry Environment

Plastic vitamin tube is used in vitamin tablet packaging due to its dry environment. There are silical-gel desiccant and large molecular sieve desiccant in plastic vatimin tube. However, silica-gel desiccant is the only one through FDA and healthy for human.

spiral desiccant closure

Silica-gel desiccant in vitamin tube is a highly active adsorbent material, which belongs to amorphous material. Silic-gel desiccant of vitamin tube cap insoluble in water, non-toxic and tasteless, chemically stable. According to diameter, silica can be divided into macroporous silica gel, coarse - hole silica gel, type B silicone, fine - hole silica gel. Silica can reuse through rebirth. The main ingredient of silica-gel desiccant is Sio2, for more translucent amorphous, composed of natural mineral processed granular or bead, usually after treatment with sulfuric acid to form, its hard, non-toxic, tasteless, non-corrosive, good chemical stability and thermal stability.

plastic vitamin C tube

Silica-gel desiccant of vitamin tube covers many hydroxyl groups with strong hydrophilicity, at the same time, the surface of silica gel desiccant has many small holes that are not visible to the naked eye, so that its surface area is greatly increased, and the properties of silica gel desiccant decide to become a good desiccant.Desiccant moisture environment as temperature of the shelf life is most suitable for 20 ~ 32 ℃, humidity was 60% ~ 60%, it can reduce the environmental relative humidity to 40%.

Xinfuda as a China major pharmaceutical packaging manufacturer with DMF, which can offer excellent desiccant packaging for vitamin tablets. Plastic vitamin tube adopted silica-gel desiccant to keep dry and the spring on the cap can prevent tablets damaging.

candy tablet packaging requirement

The health care product candy tablet refers to the health care product produced by the candy tableting process, usually generally a tablet. The purpose of the tableting process for health care products is to make the health care products tablets have a better taste and improve the user's eating experience.

effervescent tablet packaging

The candy tableting industry is gradually adopting moisture-proof dry bottles. Plastic candy tubes has good sealing performance and integrates desiccant into the bottle cap, which can effectively prevent the tablets from coming into contact with the desiccant, and can achieve the purpose of absorbing water molecules, so as to keep the inside of the package dry.

desiccant cap

The health care product candy tablet packaging bottle cap has a small drug warehouse cardboard to separate the desiccant from the test strip to prevent direct contact between the direct desiccant and the tablet. The desiccant is on the top of the lid, and the lid is directly sealed with the bottle body without the need for a gasket. The cap is made by injection molding, and the bottle body is injection-blasted. The general capacity is less than 100ml. Printing can be done according to customer requirements. The clamshell seal increases consumer appeal and is ergonomically designed to encourage consumers to close the seal and extend protection.

The advantage of vitamin tablet tube

Usually vitamin tablet tube is popular for customer, due to its' small and conventient in life. Of course the main reason is keeping tablets health and safe. The following is the advantage of plastic tube.
