Aplicació de material mèdic de butllofes de paper d'alumini

The drug packaging of aluminum foil blister is also called blister packaging, també conegut com “PTP” (Premeu a través de l'embalatge). This type of packaging has many advantages: Primer, it provides patients with multiple doses of drug packaging, que és convenient i econòmic. Segon, the aluminum-plastic blister packaging has good drug protection performance, fast production speed, baix cost, and storage space. Petit, llum, and easy to transport. Thirdly, the safety is good. Because the blister packaging aluminum foil is printed on the surface of the text, the dispenser can avoid the occurrence of wrong drugs during the dispensing process of multiple tablets.

With the “rising star” such as aluminum foil packaging, my country and the world will greatly increase high-quality blister packaging in a period of time to meet the needs of the pharmaceutical market. It is expected that packaging used for pharmaceutical blister materials will account for About 60%-70% of the pharmaceutical tablet and capsule packaging in the future is one of the pharmaceutical packaging materials with the best development prospects.

This article shares some of the development directions of blister packaging and “PTP” materials in the future based on the current domestic use of pharmaceutical foils, pharmaceutical polyvinyl chloride (PVC), adhesives and gravure inks. Most of the data comes from Internet, if there is any infringement, please contact me to delete it.

1.The materials used in aluminum foil bliste packaging also have many fine requirements.

The aluminum foil used in the pharmaceutical blister pack is a sealing material sealed on a hard piece of medicinal plastic polyvinyl chloride (PVC), so it is also called a lidding material. The aluminum foil is made of electrolytic aluminum with a purity of 99% and is made by rolling. No és tòxic, sense olor, has excellent electrical conductivity and light-shielding properties, and has extremely high moisture resistance, gas barrier properties and taste retention. Because aluminum foil has a highly dense metal crystal structure, it can block almost any gas, vapor d'aigua i llum, so it can protect the packaged objects most effectively. In modern packaging, almost all require opaque or high barrier layer, so it is widely used.

2. The most widely used blister material for pharmaceutical packaging is medicinal polyvinyl chloride (PVC) rigid sheet.

Since medicines are very sensitive to moisture and light penetration, it is necessary to have good barrier properties against water vapor, light and peculiar smell to the plastic hard film. No obstant això, the currently used polyvinyl chloride (PVC) is just not ideal on the wet and humid side, so it should be promoted in the future.

Clorur de polivinilidè (PVDC) or its composite materials. The characteristics of polyvinylidene chloride are: high polymer density, regular structure, high crystallinity, so it has extremely strong gas and gas sealing, excellent moisture resistance, good oil, chemical and solvent resistance. Especially it has excellent barrier properties to oxygen, water vapor and carbon dioxide in the air, such as polyvinylidene chloride hard film, and other plastic composite materials PVC/PVDC/PE/PVDC/0PP/PE, PVC/PE, etc. The brown composite plastic flakes are widely used in the blister packaging of medicines.

3. Farmacèutica “PTP” aluminum foil printing ink material.

En l'actualitat, hi ha molts tipus de tintes d'impressió al mercat, amb diferents marques. No obstant això, tenint en compte el procés d'impressió de medicaments “PTP” paper d'alumini i els requisits especials dels envasos farmacèutics, la tinta d'impressió ha de tenir una bona adherència al paper d'alumini, el patró de text imprès és ferm i clar, l'aplicació d'alliberament de dissolvent, i bona resistència a la calor. Excel·lent resistència a la fricció, bona brillantor, pigments no tòxics, cap contaminació dels medicaments envasats a causa de la migració de components químics a la tinta, i la viscositat pràctica ha de complir els requisits del procés d'impressió de paper d'alumini.
