Desiccant cap production process

As a component of medicinal plastic bottles in pharmaceutical packaging, the production and processing of desiccant caps are similar to the requirements of the bottle body, except that the main raw material of the bottle body is blow molding grade, while the main raw material of the bottle cap is injection molding grade.

The pharmaceutical bottle cap production process is:

First, feeding and batching are mainly conveyed to the hopper of the injection molding machine through pipes. After the machine is turned on, the material in the hopper enters the person's barrel to complete the process of feeding the machine.

Secondly, plasticization is a process in which the plastic batch material that enters the barrel from the hopper is heated in the barrel to reach a flowing state and has good plasticity. The requirement is that the plastic reaches the specified molding temperature before entering the mold cavity, and a sufficient amount of molten plastic is provided within the specified time.

Third, the first injection is to inject the well-plasticized melt into the mold under the pressure of the screw (injection process). When the melt is injected into the mold cavity, it passes through the nozzle, the main (sub) runner, and the gate. The resistance is very high. It has a large injection pressure loss of 30% -70%, so the process requires a sufficient injection pressure to ensure complete mold filling. This is followed by the molding stage, which consists of four steps: disposable mold, compaction, reverse flow and gate curing. The plastic melt injected into the mold cavity is cooled and shaped into a plastic cover.

Fourth, cooling and demoulding. Mainly refers to the stage from when the plastic in the gate is completely frozen to when the lid is released from the mold. Demoulding can be divided into two types: strong demolding and spin-off.

It is necessary to grasp the various production links and avoid problems before they can produce medicinal bottle caps that the customers of high quality can trust.

The child resistant cap bottle with desiccant cap

The new design of the child proof bottle is based on safety and prevents people other than the patient from eating, especially in children and mental patients.
At present, ordinary packaging bottles are generally sealed by aluminum foil gaskets to ensure the sealing property, but after the gasket is opened, the sealing effect is not guaranteed, and the tablets and capsules are frequently opened in the bottle cap, and the sealing is not good. Will cause the drug to absorb water or oxidize. Therefore, relying mainly on gasket sealing, there are great hidden dangers. Secondly, when the cap is frequently opened, moisture will invade the bottle and accelerate the deterioration of the drug. In particular, such as aspirin, sodium phenobarbital, effervescent tablets, test strips, etc., are prone to deformation or deterioration after moisture absorption, and must be packaged in a bottle with good sealing properties.
Therefore, the special point of the special screw cap safety bottle is combined with the dual function of preventing moisture and opening, ensuring that the medicine remaining in the bottle after opening is still in a relatively sealed state during the use of the medicine; The risk of children accidentally opening and eating drugs.

How to protect pharmaceuticals against moisture and oxygen?

There are multiple ways for moisture and oxygen to enter the inside of a plastic pharmaceutical bottle which can cause a drug to lose its efficiency before the end of its shelf life.So an effective way and packaging is important for medicine. Xinfuda offer the solution including silica gel and molecular sieve desiccant, as well as barrier bottles and oxygen scavengers enable the control of conditions inside drug packages.

desiccant polymers caps aganist moisture and oxygen

Moisture and oxygen can affect the chemical or physical stability of pharmaceutical products. Due to moisture vapor transmission, tablets and capsules are exposed to moisture and oxygen that can permeate the package from the outside environment. Sensitive healthcare products often need active protection to adsorb these elements to ensure optimal shelf life.

Xinfuda mainly adopts closures with desiccant polymers to address special packaging needs.
