Which material is used for the effervescent tablet bottle to have a better sealing effect

The effervescent tablet bottle is a special functional packaging for effervescent tablets. In view of the particularity of the effervescent tablet performance, this kind of packaging has extremely high requirements for sealing, so what kind of material can the effervescent tablet bottle use? What about a better sealing effect?

Bottle body: polypropylene

At present, the common basic effervescent tablet bottle on the market is mostly made of polypropylene. Polypropylene (PP) is one of the four general-purpose thermoplastic resins. It uses propylene as the raw material and ethylene as the comonomer through polymerization. Prepared by reaction production. This material has the following performance advantages:

(1) Non-toxic and odorless: Polypropylene is a colorless, odorless, non-toxic, and translucent solid substance, which fully meets the requirements of safety, non-toxic and non-polluting of pharmaceutical packaging materials;

(2) Lightweight: The relative density is small, only 0.89-0.91. It is one of the lightest varieties in plastics. The material is light and easy to carry.

(3) Moisture-proof: good moisture-proof ability, can prevent peculiar smell from penetrating, and guarantee the medicine properties of medicine

(4) Heat resistance: high heat resistance, it will not be damaged when sterilized in steam at 135°C for 100 hours;

(5) Stable: Good chemical properties, almost no water absorption, and no reaction with most chemicals.

In view of the above advantages, polypropylene material is the best choice for the effervescent tablet bottle.

Desiccant cap: low density polyethylene

Due to the high hardness of polypropylene material, which is not conducive to the tightness of the packaging, the cap of the effervescent tablet bottle is made of low-density polyethylene with a relatively soft hand. Polyethylene (referred to as PE) is a kind of ethylene made by polymerization Kind of thermoplastic resin. Low-density polyethylene is tasteless, odorless, non-toxic, matt surface, milky white waxy particles, good toughness, density about 0.920 g/cm3, melting point 130℃～145℃. Insoluble in water, slightly soluble in hydrocarbons, toluene, etc. It can withstand the erosion of most acids and alkalis, has low water absorption, maintains flexibility at low temperatures, and has high electrical insulation.

Effervescent tablet packaging

The effervescent tablet tube uses a combination of polypropylene with good moisture resistance and low-density polyethylene with good toughness to meet various requirements of the basic effervescent tablet for airtightness and moisture resistance, making the basic effervescent tablet bottle reach The better sealing effect effectively guarantees the safety and efficacy of the medicine, and these two materials are widely used in life and are cost-effective, and have been favored by many effervescent tablet manufacturers.
