Advantages and applications of Ziplock bags

Ziplock bags are a cost-effective and versatile packaging option for both food and non-food items. This type of packaging is an ideal fit across a host of industries, within retail and for private use at home.

Ziplock bags are also known as grip seal bags, supagrip resealable bags, plastic seal bags and seal again bags. Not only are they a great option for organising various items, but here at Transpack, our seal again bags are highly robust and can be used again, making them an eco-friendly, cost-effective packaging solution.

There are countless uses for our range of Ziplock bags. To help inspire you, we’ve compiled some top tips to showcase the many advantages of this packaging and the many applications that our handy Ziplock bags can be used for.

Easy grip seal

How do Transpack’s seal again bags work? The grip seal can be easily set to the closed position by simply applying pressure to either side of the grip. The secret to our resealable bags is this simple squeeze and pull apart top, which enables these handy bags to be used again and again.

Our grip seal bags are easy to open and user-friendly, thanks to one side of the header being slightly higher than the other.

Eco-friendly packaging

Here at Transpack, we pride ourselves on our environmentally friendly ethos, and this is reflected in our range of eco-friendly packaging options. Our grip seal bags can not only be used time and time again due to their grip seal closing, they are also recyclable once ready to be disposed of. We also have a range of biodegradable Gripseal bags which have an additive making them oxo-degradable – they will break down in a matter of months once disposed of.

Bulkier items
Our premium range of seal again bags are made from high quality 200 gauge (50 micron) polythene, and are far stronger than the more commonly found 160 gauge (40 micron) bags. Our robust Heavy Duty resealable bags (350 gauge / 88 microns) are the perfect solution for the storage of bulkier, heavier items.

From electronics and toiletries to weighty foods and medicines, our sturdy resealable bags offer the perfect solution for the safe storage of bulkier items.

Gift bags
Transparent and secure with their grip seal, our seal again bags make for perfect gift packaging.

From confectionary to toiletries, stationary to cosmetics, our seal again bags can be used to showcase a range of gifts. These sturdy bags can also be overprinted, and if you’re looking for large Ziplock bags, they can be made to a bespoke size. Contact us for a quote today.
