High-Performance Lidding

Lidding offers protection and tamper resistance.



Unembossed lids include an improved peel for easy opening, clearer graphics, no shadow effects, and higher tear resistance. Separation points on the foil allow for good reproduction of graphic images and text due to uninterrupted light reflection. The lids can be made on traditional packaging machines. The properties of the un-embossed lids also reduce most packing materials and storage costs by up to 50%, according to the company. Constantia, Barrington, IL; 847/713-2200; bniriz@aol.com

Die-Cut Lids

Sterilizable die-cut lids are available with short lead times. Coated Tyvek, medical-grade papers, films, and foil laminates may be printed in up to four colors and die-cut for sealing to a wide range of medical rigid tray materials. Die-cutting capabilities include perforations, radium corners, hole punching, and special shapes. Electronic prepress and in-house plate-making services allow for one-week turnaround from date of supplied artwork. Rexam Medical Packaging, Mundelein, IL; 973/635-0171; www.

Blister Foils

A line of blister foils can be sealed to Aclar high-barrier films. Pharmaceutical manufacturers are now in a position to invert the lamination film and thermoform blisters with Aclar-In, resulting in improved barrier properties of the total package. Current pharmaceutical applications include peelable child-resistant foil as well as unsupported aluminum push-through foil. Other lidding materials will be introduced according to market demands.

Induction Seal

A holographic induction seal provides a high level of security for bottles or containers. Using an induction seal process, this application provides very effective protection for authentication, tamper resistance, and branding. A holographic layer becomes part of the seal itself. HoloCap can be combined with other security needs in packaging for pharmaceuticals and other industries. HoloCap is an easily recognized effective device for a wide array of consumer packaged goods.

Lidding Material
A manufacturer of high-performance, flexible packaging materials for the pharmaceutical, medical, and healthcare markets has engineered a new lidding material for thermoformed cups. The paper/polyester/coex sealant structure can be sealed and peeled to polypropylene, high-density polyethylene, or high-impact polystyrene thermoformed cups. The paper layer features a clay coating, which enhances printing by either flexographic or rotogravure methods. It can be sterilized using gamma or EtO methods.
