Packaging Resource Center: The Latest in Bottles and Closures

Vials for Injectables

Cyclic olefin copolymer (COC) vials for injectables feature thermoplastic elastomer (TPE) caps. The Diabolo vials and caps are manufactured in a cleanroom environment and are sterilized so that they do not require any additional processing before filling. The COC vial is filled through the TPE cap and the hole is then resealed with a laser. The concept was brought to the vial manufacturer by a filling equipment manufacturer.

Bottle Decorating

A company offers a range of services to facilitate strong product brand identity. Services include silk-screen, ceramic, and acid-frosting decorating. Silk-screening is available for most bottle types and container materials, and the service can include up to three colors. Various labeling applications are also offered.

PET Bottles

Two lines of heavy-wall PET bottles are designed to give the appearance and feel of glass without its breakability and cost. They are not squeezable. The cylindrical bottle line is available in six sizes ranging from 1 to 8 oz. The line of oval bottles is offered in four sizes from 2 to 8 oz. In addition to white or clear, custom colors are available. SeaCliff Packaging Inc., Newport Beach, CA; 949/955-1239; www.seacliffpackaging.com.

Adhesive-Free Closures

A manufacturer offers a family of closures for laboratory and pharmaceutical containers. The closures feature Cepure liners that are bonded to the closures without the use of adhesives. The adhesive-free bonding is designed to eliminate possible sources of contamination. The liners are bonded mechanically so that they will not fall out during handling. Closures with Cepure 1000 liners are available in standard constructions for pharmaceutical and reagent containers filled by single injection. Closures with Cepure 3000 liners are designed for multiple-use applications including gas and liquid chromatography equipment. The liners can bond to polypropylene and polyethylene closures.

EBM Bottles

A company offers four extrusion-blow-molding (EBM) bottle molds that feature dual chambers. Two of the EBM bottles are available in 250-ml sizes and the other two bottles can contain up to 500 ml of product. The bottles were created in response to a customer request. The design process required the manufacturer to improve its die design to achieve the desired sidewall-thickness distribution for the bottle geometry using nonoriented polyethylene terephthalate glycol (PETG). The process can potentially be applied to stretch-blow-molding PET. Alcan Packaging—Plastics Americas, Pennsauken, NJ; 856/661-1020; www.alcanpackaging.com.

Colored cPP Bottles

A manufacturer has developed clarified polypropylene (cPP) bottles for packaging various moisture-sensitive tablets and capsules, nutraceuticals, and vitamins. The bottles are designed as lightweight alternatives to PET and high-density polyethylene bottles. The bottles are designed to provide the same gloss, clarity, and shine as PET bottles, but they offer an improved moisture-vapor transmission rate. They are available in eight sizes ranging from 75 to 500 cm3 and a range of transparent colors, including blues, greens, reds, and ambers. Opaque colors such as gloss black and white are also offered. The bottles are produced using a single-stage injection-stretch-blow-molding (ISBM) process.
