When colours PMS colours , it is recommended that you use a PMS color chart.

What are PMS colours? PMS stands for Pantone Matching System. colours also colours as Pantone colours. PMS colours standardized colours the ink is mixed in advance to achieve the exact colour. What is the PMS color guide used for? A PMS color guide is a collection of color swatches. The PMS color guide is used to colour a colour . Each colour the guide corresponds to a code.
This color code can then be used in graphic design software.

Safety first
The Product Safety Act always raises many questions, which we are happy to answer as follows to the best of our ability: it is still unclear which products require a safety warning, because how are they supposed to print the regulations on a staple with advertising, on ballpoint pens, or on our balloons or party picks?

It’s just as strange to print a safety warning on balloons stating that they must be inflated with a pump and require adult supervision, when this safety warning can only be read once the balloon has already been inflated! This safety statement, along with our other instructions, is always printed in multiple languages on our balloon packaging (PE and PP bags) as standard. Do you want your customers to be able to identify which manufacturer produces the products for you? No! That’s why only our production code NL7532SH is indicated on our balloon packaging, party picks, etc., meaning that only you can recognize that we are the manufacturer. For example, if you order paper flags, sun visors, pinwheels, or other products, we can always print your own branding (such as your company logo or website) for you at no extra cost.

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

Will you choose green too?
Products and services bearing the EU Ecolabel are produced in a more sustainable manner. The label therefore sets strict requirements regarding the use of raw materials, energy, water, hazardous substances, waste, and packaging.
The EU Ecolabel is the official European environmental label 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. All you have to do is look for the flower logo. Only products that meet strict environmental and quality standards can be certified.

Bamboo and the Environment
Land degradation is estimated to cost the global economy $2.3 trillion annually over the next 30 years. Bamboo offers a solution.
Bamboo is a grass, and all 1,640 species have a strong root system that binds the soil. It is a very fast-growing plant that is best suited for restoring unproductive agricultural land, controlling erosion, and stabilizing slopes.

35% more oxygen
A bamboo forest absorbs 5 times more CO2 and produces 35% more oxygen than an equivalent area of tree forest. Each hectare of bamboo forest absorbs 1,000 tons of CO2 per year.
After 2 to 5 years, the bamboo stalk is fully grown and ready for harvest. Assuming a 4-year growth circ. , 25% of the bamboo forest can be harvested each year without any decline in circ. .

Because so much CO2 is absorbed during growth, bamboo is much better for the environment than tropical hardwood—even after the bamboo stalks have been transported and processed into compressed bamboo.

The pulp used for our napkins is bleached using the ECF (Elemental Chlorine Free) process, which employs oxygen and other chlorine-free chemicals such as chlorine dioxide (ClO₂), hydrogen peroxide (H₂O₂), and ozone (O₃). This process is more environmentally friendly than traditional bleaching with elemental chlorine, as it reduces the formation of harmful dioxins and other persistent organic pollutants.

Colour / cardstock

For our products, the base material for cardboard and paper is always white.
Colored paper or cardboard is not available.

Non-flammable, non-explosive
All balloons we supply can be filled with helium gas. Helium gas is a natural noble gas that is non-flammable, non-explosive, and non-toxic, and is a component of our atmosphere. Authorized gas suppliers are happy to assist you with its delivery and usually provide a filling valve to make it easier to fill balloons yourself.


's Floating Time Since helium is extremely volatile, its shelf life is limited compared to balloons filled with air. Up to 12 hours for the 85/95 balloon size. Therefore, balloons filled with helium gas float for only a few hours (depending heavily on the chosen balloon size).


Inflation Method The inflation method is also extremely important: never inflate a helium balloon to 100% capacity; approximately 80% of the balloon’s actual capacity is sufficient. Since a balloon can rise to heights of many thousands of meters, it will expand in the atmosphere and thus have sufficient “space” to expand, making the chance of drifting far greater than with a 100% filled balloon. Also, never add air to the balloon filling (to potentially save money), as this does not benefit the balloon’s lift. Giant balloons, on the other hand, have a significantly larger capacity compared to normal balloons and therefore remain aloft much longer.

Recommendation:
We recommend an 85/95 cm balloon as the minimum size for helium filling


Balloon Decorations We recommend inflating the balloons as close to the time of use as possible. If you fill balloons with helium today, they will definitely be lying on the ground by tomorrow! However, this has nothing to do with quality, since they stay inflated for weeks when filled with air. Helium escapes through the pores of the natural latex.

DON’T LET THEM GO!
Wisa Enschede does not endorse the release of balloons. We advise against releasing helium-filled balloons to prevent environmental pollution and to ensure they do not end up in the atmosphere (however, releasing balloons is not prohibited by national law).

Helium gas is available exclusively from locally authorized gas depots.

Uninflated latex balloons are durable. When balloons are inflated, their surface area increases by about 15 to 20 times, causing them to age much faster than uninflated balloons because they are under tension. This tension causes the material to break down slowly.

UV radiation
When used outdoors, the quality of the balloons deteriorates even more rapidly. In the case of balloon decorations, etc., the aging process begins very quickly and accelerates even further at elevated temperatures. Air conditioning systems, for example, can also create an atmosphere that is highly oxidizing for balloons, as can other external factors such as UV radiation, daylight, sunlight, etc. As a result, the “glossy effect” of the balloons as you received them is quickly lost, and they may also pop more easily. Unfortunately, this cannot be prevented with any balloon, anywhere in the world.

Ozone is a real “rubber killer.” When exposed to high levels of ozone, natural latex can develop a strong, distinctive odor, and micro-cracks may form, which attack the surface of the balloon and further accelerate the aging process—potentially leading to leaks or the balloon bursting.

If you want to store and hand out balloons in a store, we recommend using a balloon tree. Placing them on the floor is fine on carpeted surfaces, but on stone, concrete, or wood floors, the very thin balloon walls may not be able to withstand the pressure, and the balloons could pop.

Shelf Life of Balloons
A general shelf life cannot always be specified, as storage conditions play a major role. That is why you will always find a packaging date and warning text on our balloon packaging, as well as storage and shelf-life recommendations stating that balloons can be stored for up to 1 year, provided our recommendations are followed (see also the packaging text). Failure to follow these recommendations will accelerate the aging process.

Storage of Uninflated Balloons
When storing a supply of balloons, it is important to take into account external factors such as UV radiation, daylight, sunlight, etc. These external factors can negatively affect the quality of the colours and the printing inks.

UV rays break down the high protein content in latex and alter its structure. As a result, the latex loses its unique flexibility, making the balloon more prone to bursting. This means that a latex balloon (a 100% natural product) will completely decompose after one year, rendering the balloons unusable (the aging process itself actually begins earlier). This is due to existing production and ingredient regulations under REACH and the Toy Safety Directive, which apply to balloons, ensuring that the permitted limits regarding composition are not exceeded.

We recommend storing the balloons in a dry, dark place for no longer than 12 months (at a temperature between 15° and 20° Celsius) to prevent the latex from sticking. Please also avoid temperatures below 10° Celsius, as this will cause the balloons to harden.
