8011 H18 capsule blister aluminum foil remains the standard lidding material for solid-dose pharmaceutical packaging because it balances barrier protection, clean push-through, printability, at gastos.
Its value depends on details: low pinhole counts, controlled hardness, a clean surface for coating, a lacquer matched to the forming film, and rolls that run smoothly on high-speed blister machines.
Its limits are also clear. For extremely moisture-sensitive products or special formats such as child-resistant or peelable packs, cold-form alu-alu or laminated structures may be the better choice.
1. What does H18 mean on aluminum foil?
H18 is a temper designation meaning the foil is fully strain-hardened (full-hard) by cold rolling, without final softening. In foil, this gives the stiffness needed for a clean push-through action.
2. What thickness is used for capsule blister foil?
Capsule and tablet lidding foil is commonly about 20 sa 25 M, with other gauges available up to roughly 30 M. The right thickness depends on capsule size, pack design, and push-through requirements.
3. Ano ang pagkakaiba ng 8011 at 8021 papel de liha?
8011 H18 is a hard-temper lidding foil sealed over plastic pockets. 8021 is a soft, highly formable alloy used as the base web of cold-form (alu-alu) blisters, where the foil itself is stamped into pockets.
4. Ay 8011 H18 foil safe for pharmaceutical packaging?
It is widely used for this purpose. Safety in practice depends on the full foil structure, including lacquer, ink, and varnish, and on meeting the requirements of the customer’s market. Ask the supplier for compliance documents and a batch CoA instead of relying on general statements.
5. What is the difference between blister lidding foil and cold-form foil?
Lidding foil is thin, mahirap na, and sealed over a plastic pocket. Cold-form foil is a thicker, soft laminate that is formed into the pocket. Cold-form gives a full aluminum barrier on all sides at higher cost.
6. Why is heat-seal lacquer needed?
Aluminum cannot bond to plastic by itself. The lacquer melts under heat and pressure on the blister machine and creates the seal between foil and forming film. It must be matched to the film type, tulad ng PVC, PVDC, Alagang Hayop, or PP.
7. What is a pinhole, and how is it controlled?
A pinhole is a tiny hole in the foil that can allow moisture and oxygen in. It is controlled through clean melt practice, stable rolling, careful handling, and testing by light-box or automatic detection. Ask for pinhole data by batch.
8. Can foil with different bright and matte sides be used?
Oo nga. Double rolling naturally produces a bright side and a matte side. The coating side is chosen according to the converter’s process and customer requirement, so confirm which side should carry the lacquer.
9. Does 8011 H18 foil need printing or lacquer from the supplier?
Not necessarily. Some buyers purchase bare foil and print and lacquer in-house, while others buy converted foil ready for the blister machine.
10. How should blister foil be stored?
Keep rolls in original packaging in a clean, dry, temperature-stable area, away from oils, solvents, and direct sunlight. Avoid dents and edge damage, and use within the supplier’s recommended shelf life, especially for coated foil.
11. What is the minimum order quantity and lead time?
These depend on thickness, lapad ng katawan, ibabaw ng paggamot, and production schedule. Standard bare foil generally ships faster than custom coated or printed foil.
