Balloons filling with heliumgas

Non-combustible, non-explosive
All balloons supplied by us can be filled with helium gas.
Helium gas is a natural noble gas, non-combustible, non-explosive and non-toxic and is part of our atmosphere. Approved gas depots are happy to assist you in delivering them and they deliver
usually a filling tap, to simplify the self-filling of balloons

Hover time
Since helium has an extremely volatile property, the shelf life compared to balloons that are filled with air, but limited in the balloons can be kept, approximately 12 hours at balloon size 85/95. Therefore, balloons filled with helium gas only float for a few hours and therefore also depend heavily on the chosen balloon size

Filling method
Also, the method of filling is extremely important: Never fill a helium balloon for the full 100%. Approximately 80% of the actual balloon content is sufficient. Since a balloon can rise to many thousands of meters in height, it will expand in the atmosphere and in this way has enough “space” to expand, so that the chance of distant hovering is much greater than a 100% filled balloon. Also, never mix a quantity of air on the balloon filling (to be cheaper if necessary) because that does not benefit the rise power of the balloons. Giant balloons, on the other hand, have a substantially larger content compared to normal balloons and therefore continue to float much longer.

As a minimum balloon size for helium filling we recommend balloon 85/95 cm

Balloon decorations
We recommend that you fill the balloons as soon as possible before use. If you were to fill balloons with helium today, they will definitely be on the ground tomorrow! However, this has nothing to do with the quality, because with air they remain filled for weeks. Helium evades through the pores of the natural latex.

Wisa Enschede is not in favour of releasing balloons. Our advice is not to leave helium-filled balloons on to prevent pollution and thereby ensure that they do not enter the atmosphere (however, the possible release of balloons is not prohibited by law nationally)

Helium gas is only available from locally approved gas depots

Balloons with airfilling

The biggest enemy of natural latex balloons are warmth and direct sunbeams. On hot summer days, for example, balloons that are hung outside will therefore fade in color faster and can therefore also crack faster. In a room with a normal average temperature (without much (sun) light, the balloons usually keep their air filling for several weeks, when they are well filled and closed

All balloons are inflated by us before printing and are therefore automatically checked for their quality for an equal time, or there is not a small hole in the extremely thin balloon wall. These balloons already “crack” during printing in our printing department

Handing out balloons
If you want to hand out balloons, we advise you to use a balloon tree for this.
If you put them on the ground, this will not hurt, e.g. on carpeting, but on a floor of stone/concrete/wood, the then very thin balloon wall cannot tolerate this and some balloons will crack may be

First blow the latex balloons to the maximum size and then let about 10% escape. This relieves and stabilizes the surface of the balloon. We recommend that you do not blow the balloons larger than the maximum balloon size, because then they can snap quickly. Especially heart balloons are very sensitive to this!


Inflated balloons

Latex balloons are unexpensed durable. By inflating balloons, the surface is enlarged about 15 to 20 times, which makes the aging process much faster than inflated, because they are so under tension. Due to this tension, the material slowly breaks down

When used outdoors, the balloon quality decreases even faster in appearance. With balloon decorations etc. the aging process occurs very quickly and at elevated temperatures even faster. Air technical installations such as air conditioners can also develop an atmosphere that oxidizes strongly for balloons and other external influences such as; UV radiation, daylight, sunlight, etc. As a result, the “shine effect” of the balloons as you received them is quickly lost and can therefore also crack faster, under the influence of oxygen and ozone. Unfortunately, this is unavoidable, with any balloon anywhere in the world!

Ozone is an absolute “rubber killer.” With strong influence due to the ozone layer, the natural latex can cause a strong characteristic smell and microcracks can occur, which attack the surface of the balloon and accelerate the aging process again and can lead to leakage or the cracking of the balloon.

If you want to store and distribute balloons in a store, we advise you to use a balloon tree for this. If you put them on the ground, this will not hurt, for e.g. on carpeting, but on a floor of stone/concrete/wood, the then very thin balloon wall can sometimes not tolerate this and balloons may crack

Shelf life and storage of balloons

Shelf life of balloons
A general expiry date cannot always be specified as the method of storage is very decisive. Therefore, on our balloon packaging you will always find a packaging date and warning text, as well as a storage and expiration advice with the information that balloons can be stored for up to 1 year, taking into account our recommendations (see also the packaging text). Failure to follow this advice will speed up the aging process

Storage of inflated balloons
When storing a stock of balloons, one should also take into account external influences, such as: UV radiation, daylight, sunlight, etc. These external influences can negatively affect the quality of the colours of balloons and the printing inks

UV rays affect the large proportion of proteins in latex and the rays change the structure. As a result, the latex loses its unique flexibility so that the balloon snaps more easily. This means that a latex balloon (100% natural product) will completely decompose after a year and the balloons become unusable. (In principle, the aging process itself starts earlier). This is due to the existing production and ingredient regulations according to REACH and the toy directive under which balloons fall, whereby the permitted limit values with regard to composition are not exceeded

We recommend keeping the balloons always dry and dark and no longer than 12 months. (recommended temperature between 15° and 20° Celsius) so that the latex does not stick. Please also avoid a temperature lower than 10° Celsius, as the balloons will harden

Paper/card board

For all cardboard seams and paper types, the base material is always white
Coloured paper or cardboard is not available

Pantone colours

If you want to determine PMS colours, it is advisable to use a PMS impeller

What are Pantoe colors? PMS stands for Pantone Matching System colours are also called Pantone colours. PMS colors are standardized colors where the ink is mixed in advance to the right colour. What is the PMS range for? A PMS impeller is a color range of colour swatches. To determine a colour, the PMS impeller is used. Each colour in the impeller corresponds to a code. This colour code can then be used in the graphic programs

Product safety directive

The Product Safety Act always brings many questions, which we are happy to answer as follows, as far as this is possible for us. It is still not clear which products need a safety warning, because how do they want the regulations printed on a Paperclip with advertising, on ballpoints  or on our balloons or party pickers?

Just as strange is it to press a safety message on balloons, that “balloons with a pump must be inflated and adult supervision is required”, although one can only read this safety statement when the balloon is already inflated! For example, this safety statement, including other instructions from us, is always listed as standard in multiple languages on our balloon packaging (PE and PP bags). Do you want your customer to be recognized which manufacturer produces the products for you? №! Therefore, only our production code NL7532SH is indicated on our balloon packaging, party pickers, etc., which means that only you can recognize that we are the manufacturer. For example, if you order paper flags, sun visors, windmills or other products, we can always print your own identifications (e.g. company logo or website) for you at no extra cost

That is why the following is always of the utmost importance to us;

Please inform us to what extent we need to implement the Product Safety Info for you and let us know if you should be listed as a manufacturer/supplier or your customer’s name when placing this order. Example: (Production code: NL7532SH – produced for promotional items Jansen &Wilhelmus / www.jaundwil.nl) If you have any questions about this, or if you have information for us that may be useful, we are happy to help you

Certification and Environment

Bamboo and the environment

Bamboo and the environment
Land degradation is estimated to cost the global economy $2.3 trillion annually over the next 30 years. Bamboo is used as a solution. Bamboo is a grass and all 1,640 species have a strong root system that binds soil. It is a very fast growing plant that is best suited for the restoration of non-productive agricultural land, control of erosion and keeping slopes stable

35% more oxygen
A forest with bamboo absorbs 5 times more CO2 and produces 35% more oxygen than an equivalent piece of forest with trees. Per hectare of bamboo forest, 1000 tonnes of CO2 are absorbed per year.
After 2 to 5 years, the bamboo trunk is fully grown and can be harvested. If we assume 4 years of growth, 25% of the bamboo forest can be harvested every year without any decline in the size of the forest.
Because so much CO2 is absorbed during growth, even after transporting and processing the bamboo stalks into pressed bamboo, the bamboo is much better for the environment than tropical hardwood

Better not biodegradable






Better not biodegradable
Biodegradable plastic items and packaging are not preferred to reusable and recyclable plastic items/packaging, the Knowledge Institute packaging (KIDV) states in a press release dated 19 August 2018. The National Waste Management Plan of 18 December 2017, even says that they are not allowed at the GFT, according to the research of CE Delft, Transition Agenda Plastics and the policy on biodegradable plastics in the National Waste Management Plan. (source KIDV)

The market for environmentally conscious articles is constantly expanding and so it is becoming increasingly important for entrepreneurs in the present day to recycle and bio.
However, the question is whether the processing of, for example, cardboard cups / paper dish plates should be BIO. No, that’s the answer right now. Our cardboard cups and plates are made of paper fibers from sustainable forestry. The micro thin PE inner coating prevents soaking, for example, a cup or cardboard plate.

The Advertising Code Commission finds the slogan
“100 % compostable” misleading”

On 16 March 2020, the trade association and the largest waste processor in the field of compost RENEWI themselves admit in the Monitor/NCRV programme that the cups that are consumed by, among others, the broadcasters and the central government with millions of pieces and are collected separately according to a system, end up in normal incinerators with the residual waste and are not recycled because the solutions for this are too expensive. So it turns out that the stories about compostable cups so far turn out to be a pure marketing ploy.
Because in recent years the processes of composting plants have accelerated, the biodegradable plastic packaging no longer breaks down quickly enough and is left in the compost, according to the Afvalfonds Netherlands. If the biodegradable plastic ends up in the other plastic waste, it can affect the quality of the recyclate. Biodegradable plastic should therefore be disposed of in residual waste and not in the GFT green bin or other plastic waste. This has led the Waste Fund packaging foundation to decide. (source: VM Packaging Management) This means that BIO articles, despite being much more expensive, end up in the normal incinerator at the waste processors

Stora Enso statement
For the paper cups we only use approved raw materials for safe food contact. Manufacturer Stora Enso has tested the food and consumer safety of our plastic coated cups in accordance with Regulation (EU) No 0/2011. All Stora Enso Consumer Board products (cardboard + PE coating) are safe for the intended end use and can be safely in direct contact with food



EU Eco label

Products and services with the EU Ecolabel are produced more sustainably. The quality mark therefore imposes strict requirements on the use of raw materials, energy, water, harmful substances, waste and packaging.
The EU Ecolabel is the official European ecolabel for non-food products and services. It is supported by all EU Member States, the European Commission and Norway, Liechtenstein and Iceland.
The EU Ecolabel makes it easy to make a more sustainable choice. You just have to pay attention to the logo with the flower. Only products that meet the strict requirements in terms of the environment and quality can be certified

Toy Safety directive
