Grip Seal Bags

What Are Grip Seal Bags?

Grip seal bags are small resealable polythene bags with an integral press-together closure at the top.

To close the bag, simply press the two sides of the seal together along its length. The bag can then be pulled open and resealed whenever access to the contents is required.

Unlike a single-use adhesive closure, the grip seal can be opened and closed repeatedly.

You may also see similar products described as:

• resealable plastic bags
• resealable polythene bags
• zip seal bags
• grip bags
• reclosable bags
• plastic storage bags

They provide a simple and economical way to organise, store and package a huge variety of small items.

What Are Grip Seal Bags Used For?

One of the main advantages of a grip seal bag is its versatility.

They are commonly used for storing and organising:

• screws, nuts and bolts
• washers and fixings
• electronic components
• spare parts
• jewellery
• beads and craft materials
• stationery
• buttons
• samples
• coins and collectables
• small retail products
• instruction sheets
• labels
• cables and accessories

They are particularly useful where small components need to remain grouped together rather than loose in a box, drawer or storage bin.

Grip Seal Bags for Small Parts and Components

Workshops, engineering businesses and manufacturers can use clear grip seal bags to keep small components organised.

Screws, washers, nuts, bolts, clips and other fixings are easily lost or mixed together when stored loose.

Placing them into separate resealable bags allows different sizes or types of component to be kept together while still remaining clearly visible.

The bags can then be stored:

• inside parts bins
• in drawers
• on shelving
• within larger cartons
• alongside products or assemblies

Because the bag can be opened and resealed, individual components can be removed without needing to replace the packaging.

Clear Resealable Bags for Stock Organisation

The clear polythene construction allows the contents to be seen without opening the bag.

This can be particularly useful in warehouses, stockrooms, workshops and fulfilment operations where staff need to identify parts quickly.

Separate bags can be used to organise products by:

• size
• colour
• part number
• customer
• batch
• job
• product type

A label can also be attached to the outside where additional identification is required.

If you require bags with a dedicated writable panel, write-on grip seal bags may also be available by enquiry.

Grip Seal Bags for Retail Products

Small clear grip seal bags can also provide a simple way to group and present smaller retail products.

Possible applications include:

• craft supplies
• beads
• buttons
• small accessories
• replacement parts
• fixings
• hobby components
• stationery
• samples

Their clear construction allows customers or staff to see the contents while the resealable closure keeps the items together.

Grip Seal Bags for Crafts and Hobbies

Crafters frequently need to organise large numbers of very small items.

Beads, sequins, buttons, clips and other materials can quickly become mixed together when stored loose.

Small resealable grip seal bags make it possible to separate colours, sizes and types while keeping the contents visible.

The same principle makes them useful for model making, jewellery making, collecting and many other hobbies involving small components.

Choosing the Right Size Grip Seal Bag

Choosing a bag slightly larger than its contents usually makes it easier to insert and remove items and close the seal correctly.

Defenda Packaging currently stocks eight useful sizes:

The best size depends on both the dimensions and thickness of whatever you need to store.

Allow enough spare space for the contents to sit below the grip closure rather than trying to fill the bag right to the top.

Small Grip Seal Bags

For very small components, Defenda's smaller grip seal bags are useful for items such as fixings, craft materials, jewellery components and small spare parts.

Our smallest current size is approximately 60 x 60mm.

For items requiring slightly more depth, 60 x 75mm grip seal bags provide another compact option.

Medium Grip Seal Bags

Medium sizes are useful for larger collections of components, accessories, cables, stationery and general storage.

Defenda stocks several intermediate sizes including approximately:

• 75 x 85mm
• 90 x 115mm
• 115 x 115mm
• 100 x 140mm

Rather than choosing purely by the nominal size number, measure the item you want to store and select a bag that leaves sufficient room for the closure to operate comfortably.

Large Grip Seal Bags

For larger items, accessories or groups of components, we also stock:

140 x 140mm grip seal bags

and

190 x 190mm grip seal bags

These provide substantially more internal space while retaining the same convenient resealable closure.

Grip Seal Bags vs Peel and Seal Bags

Although the names can sound similar, grip seal bags and peel and seal bags work differently.

A grip seal bag has a press-together closure that can normally be opened and closed repeatedly.

A peel and seal bag generally uses an adhesive strip. The release liner is removed and the adhesive flap is pressed into place.

This makes grip seal bags particularly useful where the contents need to be accessed repeatedly.

Peel and seal packaging may be more appropriate where the bag is primarily being closed for dispatch.

Grip Seal Bags vs Ordinary Polythene Bags

An ordinary open-ended polythene bag normally requires a separate method of closing it, such as:

• tape
• a label
• a tie
• a heat seal
• a clip

A grip seal bag incorporates the closure into the bag itself.

This makes it particularly convenient for small quantities, reusable storage and situations where the contents need to be accessed frequently.

For long products or situations where bags need to be made to different lengths, polythene layflat tubing may be a better option.

Are Grip Seal Bags Reusable?

One of the practical advantages of the grip closure is that a bag can be opened and resealed repeatedly while it remains in suitable condition.

This makes grip seal bags especially useful for stock organisation and parts storage, where the contents may need to be accessed many times.

The service life of an individual bag will naturally depend on its use and how it is handled.

How Are Grip Seal Bag Sizes Measured?

Grip seal bag dimensions are normally stated as width x length.

The width refers to the measurement across the opening of the bag.

The length runs from below the closure towards the bottom of the bag.

When choosing a size, remember that a three-dimensional item requires more bag width than its simple face dimensions might suggest.

If the item is thick or bulky, allow additional space.
