Hydropac are delighted to finally be able to introduce to our customers, a product that we have been longing to reveal, but due to contractual obligations with a major online food provider, have been unable to… until now.

What is a Reflective Air bag?…

They are a revolutionary water and leak resistant product to both the Food, Pharmaceutical, Biotech and Medical sectors, enabling suppliers, producers, co-packers and logistics companies alike, to send products via the postal network in confidence.

The Reflective Air bags are provided in a single or double layer, heavy grade LDPE sealed bubble, sandwiched between a foil based laminate (Inside & Out), providing an extraordinary level of insulation through reflection and trapped air, at a comparatively low cost. In addition, both systems have a Self Seal Adhesive ‘Hot Melt’ strip to save unsightly and fiddly taping.

How do they Perform?…

The Reflective Air bags have been extensively tested to ensure they meet with current legislations, your logistical needs and maintaining the Chilled cold chain (2D or 3D) or Frozen cold chain (3D) over a minimum 24hr period.

Climate Chamber and customer own testing has proven, that the 2D system will perform on a UK based ‘extreme’ peak summer temperature profile for more than 24hrs and 96hrs during winter testing (held between +2˚c to +8˚). The 3D System; using the same ‘Extreme’ summer temperature profile, performed to a minimum 48hrs between +2˚c to +8˚ and in addition to a minimum of 24hrs below -12˚c, making them perfect for Frozen food deliveries.

So we urge you to test the bags for yourselves using your own product and hopefully you’ll be as amazed by the results, as we were.

So what are the 2D & 3D Variations?…

We offer this product as a 2D flat bag system in a single bubble and Single Foil laminate, which you simply spread out into the bottom of your box to form a gusseted bottom.  This is available in just the one size (Large) as we have found this size to be the best fit into a variety of box sizes, saving you the need to stock lots of different sizes.

In addition, we have also introduced a first to the UK  market, in a ready formed 3D box bottom system, using either a Double or Single layer bubble Insulate and double foil laminate, which has been developed and manufactured to fit snugly in to our own standard box sizes (Box 101, 2, 5 & 6) but of course, you may wish to have your own box size tailored for, which for a minimum commitment to 2,500 bags, we will make to order on a stock and serve basis. Both systems are provided with a self adhesive closure strip to seal the system.
