Deep Grip Pour

Deep Grip uses ISBM to create new handleware category

Deep Grip™ features a break-through process which uses injection stretch blow molding (ISBM) to create a new type of container handle.

Deep Grip technology enables significant grip depth (more than 25mm or 1-inch on either side), with an extremely thin (less than 0.3 mm or .01-inch) grip “web” thickness. (The grip web is where the hole would be in traditional handled bottles.) 

The grip is deep enough for the average hand to completely close around without fingers touching the container wall.  Comfort and handling ability is similar to that experienced with a traditional handle.

Additionally, container size capability is extremely broad—up to 6-liters or 1.5-gallons, and beyond.  Maximum bottle diameter is 220mm or 8.6-inches.

Deep Grip development is one of the first commercially-viable handle processes that harnesses the advantages of ISBM.  Compared to extrusion blow molding, which is the process traditionally used to produce most handled bottles, ISBM enables lightweighting, higher output per cavity, mechanical benefits (top/side load, drop and creep resistance) and smaller equipment footprint.

Lightweighting (20-25%) is possible because, in addition to functionality, the grip geometry also provides structural benefits which enable a reduction in bottle gram weight.

Bottles using the Deep Grip technology are made in a two-step process.  The first step is conventional stretch blow molding, followed by a proprietary secondary operation within the same machine which forms the handle.  The process is applicable to a broad range of ISBM bottle polymers including polyethylene terephthalate, high-density polyethylene, biaxially-oriented polypropylene, polylactic acid and others.

Because both the container and the handle are made from the same material, this eliminates downstream recycling issues and contributes to lightweighting objectives.

Deep Grip target markets include detergents, household cleaners, non-carbonated beverages (juices, ready-to-drink teas, water, etc.), milk, edible oil, motor oil, baby bottles and other segments which are currently marketed in containers with handles.  The technology also is suitable for dry products and wide-mouth applications. This technology is an ideal option for brand owners looking to drive weight and cost out of their containers, improve their environmental profile and facilitate product differentiation.

Deep Grip also opens the door for brand owners to explore new design aesthetics.  Containers are highly functional, while offering product differentiation. For example, there is significant flexibility on handle placement allowing the boundaries of container design to be pushed further. A variety of grip diameters and profiles are also possible.

Deep Grip technology is also ideally suited for commercialization where high clarity is desired.  For example, with larger PET containers with deeper grips, now commercially viable via ISBM, the capability opens the door to a variety of conversions.
