Both hard and soft aluminum are used for push in packaging. In the past, only hard aluminum foil was used because it was easy to break and release the drug with minimal pressure. Soft aluminum foil is considered child resistant because the film has high tensile force, so it needs more force to open. This effect can be enhanced by using laminated aluminum with pet or paper. The European pharmaceutical industry prefers hard aluminum foil with a thickness of about 20 microns.

If you want to take medicine, just push it through the hard aluminum to pass through the opening. External seals visible to consumers are usually printed. In some cases, the inside sealed with heat sealing paint may also have some words. There must be a double coat with heat sealing primer and heat sealing paint on it. The function of the primer is to ensure that the heat sealing paint is firmly attached to and aligned with the aluminum foil. In some cases, the primer will be dyed for marketing purposes. In this case, the primer is followed by heat sealing paint. If the drug is dyed, the thermal sealant can protect the drug from the color pigment of the primer. The colored pigment is placed between the heat sealing paint and the aluminum foil. Heat sealing paint, color pigment and primer must match perfectly. The use of soft aluminum is similar to that of hard aluminum foil. Use the tablet when you need to protect children from using it. It is desirable because it is soft and requires a lot of pressure to force it to open. The flexibility and thickness of aluminum foil make it more difficult for children to open.

The drug is growing rapidly as many people can afford it. With the development of technology, companies become different and customers want diversified products. This enables htmm foil technicians to innovate products while adhering to high standards.
