Package handle

Package handles, or carriers, are used to help people use

Handles can be built into a package, sometimes in the form of hand holes or hand holds. They can also be attached to a finished complete package after filling and closing, or even at the point of purchase.

The performance and design criteria for handles are often detailed in a

People have long seen a need to have package forms which are easy for people to carry and to use. Some of these, such as amphora,^[7] date from the Neolithic period. Handles have been formed into packages and containers such as pottery and stoneware. Wire, rope, and wicker have been added when needed.

Boxes

Wooden boxes often have hand holes or attached metal handles to facilitate handling. Steel boxes also frequently have attached handles or hinged bails.

Depending on the contents and the degree of handling required, reinforcement is sometimes needed to prevent tearing. Reinforcing tapes, whether pressure -sensitive or heat-activated, can be applied to boxes in the vicinity of hand holes.[14]^[15]

Separate plastic or composite fitments are also available for corrugated boxes.^[16][17]

Plastic bottles

• 
  Blow molded plastic bottle of milk with indentations for a handle
• 
  HDPE plastic bottle of milk, one US gallon
• 
  large reusable plastic bottles of water
• 
  Drain cleaner with convenience handle

Separate handles are sometimes added to a bottle, usually around the neck at the closure. This simplifies the bottle forming process and can allow use of lighter weight bottles. Several methods have been developed.^{[20][21][22][23][24]}

Bags

Many types of bags have handles to assist in carrying them. Paper, fabric, and plastic shopping bags frequently have handes to assist shoppers carry difficult loads. Large bulk bags can have lifting straps or hand-holds to allow people or equipment to lift or stabilize the load.

Multi-packs of beverage containers

Shrink wrapped Multi-packs often have open ends (bulls eyes) which can be used as handles. Methods are available to reinforce the film, if needed.^[25][26] Handles are often used on beverage carriers.

Tape handle

Another example with a shrink film package is for a tape to be applied to a film with slits cut in the film on either side of the tape. When the film shrinks, the tape does not and a handle is formed.[27] More common ( shown in photo) is for a tape strip with center portion matted out to be applied to shrink film prior to wrapping items. Again, the film shrinks but the tape does not, raising the matted out portion.

PSA tape handles can be built into a box or bag structure or can also be added after package completion.^[28] Specialized application machinery is sometimes available.^[29]

Bail handle

A bail handle consists of an open loop with ends attached to the item or package, sometimes to fixed mounts or ears. Several designs are available: bails are typically made of metal (wire) or plastic. It is a type of package handle which may be used for carrying or hanging items such as cans, pails, or jars.

Testing

Several

People can be used directly in an evaluation. Several different people can carry (and even abuse) handle and package options for subjective ratings. These can be compiled in a report.^[30]

More objective laboratory procedures are also used. Fixtured ‘’hands’’ of various designs are used to hold a handle (sometimes two handles for a box). ASTM International D6804, Standard Guide for Hand Hole Design in Corrugated Boxes, describes “jerk testing’’ by modified drop test procedures or use of the constant pull rates of a Universal testing machine. ASTM F852, Specification for Portable Gasoline, Kerosene, and Diesel Containers for Consumer Use, requires severe "jerk testing" of the handle. These test procedures are also used on other types of packages.^[31][32] Other test procedures are conducted with a static force by hanging a heavily loaded package for an extended time or even using a centrifuge.^[33][34]
