What is cold forming foil?
In cold forming foil cold forming progress, an aluminum-based laminate film is simply pressed into a mold by means of a stamp. The aluminum foil will be elongated and maintain the formed shape. These blisters are called cold form foil blisters.
What is Aluminium blister foil?
Aluminium blister foil is widely used for medicines in the pharmaceutical industry. It consists of a push-through blister, a moulded plastic with cavities for the individual tablets, and a push-through closure made of aluminium foil, which is called blister film or lid film.
What is OPA foil?
Opa / alu /pvc alu alu foil : 1. Excellent forming performance. Nowadays, cold formed foil packaging has been alias of high grade drugs. Description. Cold forming foil can absolutely resist vapor, oxygen and uv rays with good performance of aroma barrier.
What is cold form packaging?
Cold form blister packaging comes from sandwiching aluminium foil between polyvinyl chloride (PVC) and nylon films using dry bond lamination technology (AL/NY/PVC). The film laminate is pressed into a mould by a stamp without applying heat.
What is the difference between thermoforming and cold forming?
Thermoforming is a technique that involves heating sheets of PVC prior to insertion into a blister machine. Cold forming is a technique that does not involve any application of heat. Unlike the thermoforming method that uses clear PVC, this technique uses thin sheets of laminate film that contain aluminum.
Why are tablets packed in Aluminium foil?
The pharmaceutical industry uses blister packs for medicine. An aluminium foil is used to make a push-through closure called lid film or blister film. Following this, the tablets and capsules are well protected and hygienically protected. Blister packs are portable, compact and easy to handle.
Why is Aluminium used as wrapper of medicine?
Aluminum foil provides a complete barrier to light, oxygen, moisture and bacteria. Aluminum foil provides a complete barrier to light, oxygen, moisture and bacteria. For this reason, foil is used extensively in food and pharmaceutical packaging. Aluminum foil is also used to make aseptic packaging.
What is cold form blister?
Cold form blister packs are manufactured by sandwiching aluminum foil between Polyvinyl Chloride (PVC) and nylon (oPA) films using dry bond lamination technology. The film laminate is simply pressed into a mold by a stamp without applying heat. Thus the material is called cold forming blister laminate.
What is cold form laminate?
COLD FORMING BLISTER LAMINATE is one product dedicated to pharmaceutical industry manufactured by sandwiching aluminum foil between nylon (oPA) and PVC films using dry bond lamination technology.
How big is a cold form aluminum foil?

What kind of product is cold forming blister aluminum foil?
Cold forming blister aluminum foil is one product dedicated to pharmaceutical industry produced by aluminum foil between nylon (oPA) and PVC films, under using dry bond lamination technology.
Which is the best use for ALU ALU foil?
Alu Alu foil is an excellent multilayered structure designed for highly sensitive range of pharmaceutical and generic medicines which are highly hygroscopic or light sensitive and cannot be suitably packed with barrier plastic films.
Why is PVC used for cold forming foil?
PVC is very stiff and does not tend to shrink or spring during cold forming. Once the cold forming process is complete, the PVC helps the cavity hold its shape. In short, it ensures the geometric stability after cold forming. The nylon (oPA) film is mostly responsible for the multi – axial forming.
