Definitions
- the invention relates to a multilayer bag consisting of paper, which has on its inside a film web, and improved protection of the packaged goods against moisture, as well as improved ventilation during filling.
- paper sacks often have plastic films as an inner layer or between two paper layers.
- the plastic film is either provided with perforations, or needled or perforated.
- WO 98/57861 a multilayer paper bag is known, which is suitable for receiving powdery packaging material.
- the paper bag on each of its broad sides perforations in strip or strip shape at least in the plastic liner.
- these perforations or openings must have a correspondingly large diameter.
- the strength of the bag is reduced. This is particularly disadvantageous when accommodating high-weight goods.
- the object of the invention is therefore to provide a paper bag, the improved moisture protection of the packaged goods and at the same time has sufficient air permeability or venting capability when filling the bag.
- the invention is therefore a multilayer bag consisting of at least one outer and at least one inner paper layer and located between an outer and an inner paper layer a plastic layer, characterized in that the paper bag on its longitudinal side an overlap of the outer paper web and a partial overlap of the plastic web is provided and the outer paper web is partially glued to itself in the overlapping area.
- the partial bonding of the outer paper web takes place on two substantially mutually parallel lines, wherein the
- Glueing points can be arranged at the same height next to each other or offset from one another.
- the partial bonding can take place in a line.
- the distances between the gluing points or the distances between the partial gluing lines depend on the consistency and weight of the product.
- the inner paperboard web is connected continuously in its longitudinal overlapping area, for example by gluing.
- the individual layers of the bag are advantageously at least partially connected to each other.
- plastic liner is fixed in the finished bag by simply overlapping.
- Plastic liners of polyolefins such as polypropylene, polyethylene, their copolymers or mixtures are suitable as plastic liners.
- the thickness of the plastic intermediate layer is preferably about 10 to 100 microns.
- the outer paper layer may have a plastic coating, wherein a coating-free edge strip in which the partial bonding is carried out must be provided.
- the bag can be further layers, for example another
- outer and / or inner layer of paper can be made of several layers.
- the bag according to the invention is particularly for products containing a
- Examples of products that are filled and packaged in the bag according to the invention are, for example, cement, mortar, building aids, chemical products, food or feed and the like.
- the sack can be block bottom bag, cross bottom bag gusseted bag or pouch.
- Figures 1 and 2 show a section of the embodiments of the multilayer paper bag according to the invention in plan view. Shown is the
- FIG. 3 shows an embodiment in cross section. designations:
- the inner layer consisted of highly porous sack paper (80 g / m 2 ).
- the bag was filled with 30 kg adhesive plaster.
- the inner layer consisted of highly porous sack paper (80 g / m 2 ).
- the bag was filled with 30 kg adhesive plaster.
- the inner layer consisted of highly porous sack paper (70 g / m 2 ).
- the bag was filled with 30 kg adhesive plaster.
