DOUBTS ABOUT OUR CARDBOARD PRODUCTS

What type of cardboard does Celulosa Gallur offer? Does it meet the necessary quality standards to protect products adequately during transportation and storage?

We manufacture 100% recycled cardboard, in weights ranging from 250gr/m2 to 850gr/m2.

Our cardboard (solid cardboard, which is the term used by customers from other countries) is a high-quality solid cardboard, and our interlayers (interlayer, layerpads) offer our clients maximum cost-effectiveness when used for storing or transporting their finished product.

Does the cardboard offered by Celulosa Gallur have properties that make it resistant to humidity, or can it be treated to improve its water resistance?

Due to innovation in our process and in collaboration with the best partners and collaborators, we are capable of developing/manufacturing a multitude of cardboards, including those with water resistance for packaging.

Is the provided cardboard suitable for safe and stable stacking of packaged products?

The quality of cardboard we manufacture, which we refer to as “CUERO PAJA” at Celulosa Gallur, is made with the necessary proportion of long paper fibers to make our product a solid and safe cardboard for the transportation and storage of any item.

Does the cardboard comply with specific industry requirements and regulations, such as food safety standards or packaging requirements for chemicals?

The use of recycled cellulose fibers is continuously increasing for clear environmental reasons known to all, and this trend should be encouraged. Paper and cardboard articles obtained from recycled cellulose fibers and intended for contact with food must have a specific purity in the final product to ensure they do not pose a risk to the consumer.

Recycled cellulose fibers obtained from recovered paper and cardboard cannot be freely used for manufacturing paper and cardboard intended for contact with food. Certain sources of recovered paper and cardboard may contain contaminants that pose a risk to the consumer if they come into contact with food, although this might not be the case for other uses. Examples of such cases include those where they have been used to contain chemicals, originated from landfills, or come from clinical waste.

At Celulosa Gallur, our sources of raw materials are packaging and cardboard manufacturing industries, with materials previously selected by our suppliers. Therefore, the cardboard we manufacture complies with the European Guidelines for food contact, and we certify it through various analyses conducted by external laboratories to ensure certainty and safety.

Is the cardboard compatible with automated packaging machines used in the industry? Can personalized adaptations be made if necessary?

The recycled cardboard we manufacture is compatible with automated packaging machines. We produce interlayers/interlayer/layer pads that are used in automated lines by robots, providing the required solidity and stability.

Additionally, we manufacture cardboard with satin and smooth finishes on the faces for the packaging industry, and we offer personalized finishes based on our client’s usage and requirements.

Does Celulosa Gallur’s cardboard offer special features such as fire resistance, resistance to corrosive chemicals, antistatic properties, etc.?

We manufacture 100% recycled cardboard, and we can incorporate or develop specific properties in the paper with the application of food-grade products, as we work with partners with whom we have developed safe products for human use.

All the products we add to the recycled cardboard are safe for humans, and their purpose is solely for the recovery of fibers in the water from the manufacturing process.

Regarding the price, are there volume discounts or long-term agreements?

We offer our customers who require large quantities at different plants in different countries a regular and stable supply without stock breakages through commitment agreements.

How long does it take to receive the cardboard products once the order is placed? Does Celulosa Gallur have the capacity to meet tight delivery deadlines?

The average time in Spain is 1 week, and in Europe, it ranges from 7 to 15 days.

In the Middle East and the Mediterranean, we can supply the products within one week beyond the vessel transit time. For example, if a vessel takes 15 days from Barcelona to Alexandria (Egypt), at Celulosa Gallur, we can commit to loading the products in our warehouses in less than 1 week to ensure timely delivery before the vessel’s departure.

We have a special partner for international shipments, which is flexible, dynamic, and offers the best prices in the market.

We meet any deadline proposed by our clients. Our differentiator is our dynamic and flexible approach.

DOUBTS ABOUT LAYER PADS

What materials are used to manufacture the layer pads? Are they recyclable materials or from sustainable sources?

We manufacture layer pads using 100% recycled cardboard sourced from packaging industries and recoverers who recycle, separate, and produce the material following the established UNE standards for paper recovery.

Recycled paper is the most sustainable product due to the countless recycling cycles that can be achieved.

What is the standard thickness of the available layer pads? Can the thickness be customized according to the needs?

For beverage can manufacturers, there are international agreements on the weights (measured in grams per square meter) and thicknesses of the cardboard and paper used. However, we manufacture layer pads according to the demands and needs of the customer. This includes one-way interlayers, which are not intended to be reused, as well as interlayers for smaller cans, such as those used for heavier items that require thinner and lighter materials, etc.

We can customize the thickness based on the specific requirements and preferences of our clients.

What dimensions are available for the layer pads? Can they be adapted to the sizes of the products to be packaged?

While there are standardized measurements, we can adapt to the specific measurements and cutting requirements of our customers. To achieve this, we have developed two cutting lines using die-cutting machines, making us the most versatile and flexible manufacturer of recycled cardboard for layer pads in the market.

We can customize the dimensions of the layer pads to meet the individual needs and requirements of our customers, providing a tailored solution for their packaging needs.

What is the load capacity of the layer pads? Can layer pads be manufactured with a specific load capacity according to the needs?

The load capacity is defined by the customer based on the product they want to package or store using our layer pads. It is also determined by the customer’s specific use in their production line, considering the automation and robotization characteristics of their process.

We can manufacture layer pads with a load capacity tailored to the specific requirements and intended use of our customers. Our aim is to provide a solution that perfectly suits their packaging and storage needs, ensuring optimal performance and protection for their products.

How is the design of the layer pads? Do they have slots, perforations, or other features to facilitate handling and use? Can the designs be customized according to industry requirements?

The design of the layer pads is defined by measurements of length, width, and corner cut radius. We can incorporate slots and cuts as required by the customer. Additionally, we can make any corner cut that our customer needs for the palletization of their product.

For example, the corner design and radius required for beverage cans may differ from those needed for infant milk cans. Therefore, we can customize the design of the layer pads to suit the specific requirements of our customers, ensuring optimal fit and functionality for their packaging needs.

Do the layer pads provide stable and secure separation between the packaged products? Do they protect the products from compression, crushing, or damage during transportation and storage?

Our solid layer pads (known internationally as solid layer pads among can and food product manufacturers) are manufactured from recycled cardboard and ensure stability in the palletized product. They protect against compression and crushing while providing safe depalletization for the packager or end customer of our can-manufacturing client.

For example, if our can-manufacturing client were to use corrugated cardboard, when the cans arrive at COCA COLA for filling on the production line, they would not be easily depalletized, causing line stoppages because the cans do not slide smoothly on a surface that is not solid and uniform.

Do the layer pads comply with specific industry requirements and regulations, such as food safety standards or packaging requirements for chemicals?

Our layer pads, manufactured from recycled cardboard, comply with the guidelines set by the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) regarding the use of paper and cardboard made from recycled cellulose fibers for contact with food.

We validate this compliance through annual analyses of the recycled cardboard used in the manufacturing of the layer pads, conducted by external laboratories. Additionally, we have a Good Practices guide for our 100% recycled cardboard production process.

Can logos, product information, or other details be printed on the layer pads? Are customization services offered according to industry requirements?

In the development of our 2 cutting lines for layer pads, we have printers available to create logos, drawings, or numbering as required by our customers. In addition to printing our customer’s logo or name, which aids in the recovery of their used layer pads by their customers, we also print lot numbers to provide traceability of our layer pads to our customer.

We offer any differentiation that our customer can think of or require, ensuring that our layer pads are fully customized to meet their specific needs and preferences.
