[0002] There has long been a need for a biodegradable, compostable capsule material suitable for the high mechanical demands of capsule manufacturing. The material must be elongated without tearing, maintain sufficient structural integrity during use, and decompose rapidly under industrial composting conditions. Furthermore, the manufacturing process should allow for efficient capsule production while preserving the capsules' barrier properties, particularly in beverage or food preparation systems. SUMMARY OF THE INVENTION

BRIEF DESCRIPTION OF THE FIGURES Fig. Figure 1 shows the perforation force measurements for dry and wet capsules compared to a reference. The data show increased perforability with wet capsules, which require lower average forces for both partial and complete perforation. In particular, it shows Fig. 1. Perforation force measurements for dry and wet capsules compared to a reference. Dry capsules required an average force of 12.2 ± 0.5 kg for partial perforation (A and C) and 13.1 ± 0.5 kg for complete perforation (positions B and D). In contrast, wet capsules showed an increased tendency to perforate, requiring lower forces of 8.1 ± 1 kg for partial perforation (position F) and 10.1 ± 1 kg for complete perforation (position E). These results demonstrate that moisture content significantly influences the mechanical perforation resistance of the capsules.

DETAILED DESCRIPTION OF PREFERRED EXECUTION FORMS

[0006] The present invention addresses this unmet need with a novel compostable paper material intended for use in the manufacture of capsules, particularly those compatible with coffee machines. The capsule consists of two layers of multilayer paper processed to form both the capsule body and a cavity for holding beverage or food ingredients such as roasted and ground coffee. A key feature is the rim, created by welding the two layers together, which exhibits a treated area with reduced porosity and improved physical properties such as increased stiffness and brittleness. Crucially, the paper material possesses a unique degree of elongation—approximately 15% in the grain direction and 5% in the transverse direction—enabling the production of clearly defined capsule shapes without compromising structural integrity.This mechanical flexibility, combined with compatibility with forming processes, improves barrier properties by reducing water absorption and enhancing sealing performance during brewing. In addition to its structural advantages, the capsule meets the ISO 14855-1:2012 standard for compostability, achieving over 90% decomposition within six months and being fully recyclable, thus offering a comprehensive solution for both functional and environmental requirements.

[0009] In this production process, particular attention is paid to the formation of the weld seam during the stretching process. This seam is crucial for both the strength and impermeability of the packaging. During stretching, the edges of the paper are melted to form a uniform seam that bonds the fibers and ensures a strong weld that is resistant to moisture and air. The seam increases mechanical strength and prevents tearing and deformation during handling, transport, and storage. It also improves impermeability, preventing the penetration of moisture, air, and contaminants, which is essential for packaging sensitive products.

[0010] The welded rim also plays a crucial role in improving the capsule's seal when inserted into the coffee machine. By ensuring a particularly secure seal, the rim prevents air from escaping during the coffee extraction process. This tight seal guarantees optimal pressure retention, resulting in a more controlled and consistent brewing process. Consequently, the coffee is extracted more efficiently, leading to a richer, fuller flavor and a superior brewing experience.

[0011] The following section describes a multi-layered packaging system consisting of compostable and food-grade materials, with each layer selected from an approved group of commercially available products with proven environmental compatibility. The structure is designed to balance printability, barrier properties, adhesion, and mechanical integrity, while maintaining compliance with international standards for compostability and food contact.

[0012] It will now be on Fig. 1. Referenced. To evaluate the mechanical perforation resistance of capsule structures, a series of tests were conducted under dry and wet conditions. In the dry state, the capsules required an average force of 12.2 ± 0.5 kg for partial perforation (positions A and C) and 13.1 ± 0.5 kg for complete perforation (positions B and D). In contrast, wet capsules exhibited lower resistance, with partial perforation occurring at 8.1 ± 1 kg (position F) and complete perforation at 10.1 ± 1 kg (position E). These results demonstrate that moisture content significantly reduces the mechanical strength of the capsule, a critical factor for applications requiring structural integrity under humid conditions.

[0013] It will now be referred to as Fig. Reference is made to Figures 2 to 5, which illustrate the properties of various paper configurations under tensile stress. The present invention relates to a multilayer paper product designed to have controlled tensile elongation properties in both the grain direction (MD) and the cross direction (CD). In particular, the paper has an elongation at break of approximately 15% in MD and 5% in CD, enabling it to withstand directed mechanical loads without loss of structural integrity. These properties are achieved through precise fiber alignment, bonding techniques, and multilayer compositions.

[0014] It will now be on Fig. Reference is made to Figure 6, which shows an FT-IR spectral analysis of the inner and outer layers of the multilayer paper. This analysis confirms the chemical composition of the material by means of µ-ATR testing between 4000 and 400 cm⁻¹. -1The paper product according to the invention is over 90% compostable and recyclable and, unlike prior art solutions such as those disclosed in WO2024100283A1, combines high elongation with ecological sustainability.
