Abstract
A recyclable blister pack system is provided, including a substrate having a dry tack adhesive layer deposited on one of its surfaces and a blister layer for receiving a product. The properties of the dry tack cohesive are selected so the blister layer is separable from the substrate without leaving substantial substrate residue on the blister layer. This improves the recyclability of the blister layer.
Description
- The present application claims the benefit of U.S. provisional application Ser. No. 60/999,329, filed Oct. 17, 2007.
- The present invention relates to an easily recyclable blister pack system and to the process of making.
- Consumer packaging has evolved from simple cartons that protected the product, but which required opening the carton to view the contents, to blister/card packages that encapsulate the product while still allowing viewing the product, to thermoformed clamshell containers that allow tamper-proof viewing of the finished product. Each step in the evolution of the packaging has increased the cost of the package, the amount of hydrocarbons required for manufacture, and reduced the opportunity for recycling the packaging materials following removal of the product.
- In the case of card/blister packages, the product is inserted into a thermoplastic blister that is then heat-sealed (at elevated temperature and pressure) to a printed chipboard card that has been coated with a heat-sensitive adhesive. When the product is removed from the package, the adhesive and fibers bond to the blister, and prevent efficient recycling of the blister material. In addition, the card/blister packages are subject to size and weight limitations because the assembled package must fit into heat-sealing machines.
- In the case of clamshell packages, the product is inserted into a transparent thermoplastic shell that fully encloses it. The shell consists of two halves joined by a hinge made of the materials found in the shell. The clamshell is folded in half to form an enclosure that completely encloses the packaged product. The two halves of the assembled halves, or by means of a mechanical fastener such as a staple. For heavy or high value products, the shell may be heat or radio frequency (RF) sealed for tamper resistance, but the heat-sealing operation frequently causes customer dissatisfaction due to the extreme difficulty in opening the pack to use the product. In addition, the clamshell package uses two to three times the hydrocarbons required for a card/blister package. The clamshell materials are not easily separable for recycling.
- Consumers are increasingly concerned with the excessive amounts of plastic, cardboard and paper associated with the packaging of consumer products, as are various enviromental conservation groups. Some major consumer product retailers have also expressed dissatisfacton with currently available consumer product packaging options, especially those with a high impact to the environment.
- One such national retailer has developed a “sustainability scorecard” that measures the environmental impact of the packaging used for consumer products. The sustainability scorecard is used to reward suppliers that have developed or utilized sustainable packaging products and technology. Suppliers that do not use sustainable packaging will be at a competitive disadvantage.
- By way of example, the sustainability scorecard oncludes the the following factors that are considered: greenhouse gasses (e.g. carbon dioxide (CO2) created per ton of packaging production, material value, product-to-package ratio, cube utilization, cost of transportation, total recycled content, recovery value, renewable energy use in production, and innovativeness.
- Accordingly, there is a recognized need for new packaging products and packaging manufacturing techniques that minimize impact to the environment throughout the entire life cycle of the product from manufacture through sale, use and ultimate disposal.
- It is an object of the invention to provide a packaging system that meets the sustainability scorecard targets and offers significantly improved recyclability
- The present invention provides an easily and efficiently recyclable packaging system for consumer products capable of incorporating full color graphics, tamper and theft resistance, use of recycled materials (SPET bilater and post-consumer corrugate) and a dry tack cohesive adhesive. The packaging consists of these components; a die-cut substrate (a corrugate body in the preferred embodiment), a thermoformed RPET blister layer, and a dry tack cohesive adhesive.
- In its simplest form, the invention comprises a substrate having first and second regions, a dry tack cohesive layer applied to the first and second regions, and a blister layer for accepting a product and having a surface along its periphery capable in use of capture between the dry tack cohesive layers. The adhesive properties of the cohesive layers are selected such that it is capable of forming a seal only with itself and the substrate, and so it is separable from the blister layer without leaving substrate residue to facillitate recyclability.
- In the preferred embodiment, the invention comprises a blister pack system including a substrate having a first and second regions with at least one of the regions having an opening formed therein for receiving a product, a dry tack cohesive layer applied to the first and second regions, and a blister layer shaped to accept a product and having a surface along its periphery capable in use of capture between the dry tack adhesive layer on the first and second regions. The adhesive properties of the cohesive layer are selected such that it is capable of forming a seal only with itself and the substrate, and so that it is separable from the blister layer without leaving substrate residue to facilitate recyclability.

FIG. 1 shows aplanar substrate 10, which is the preferred embodiment is corrugate body having a generally rectangular shape, but which can also be a chipboard material. Although not shown inFIG. 1 ,substrate 10 may be pre-printed with a color graphic label describing the product (also not shown), The substrate is generally divided into two halves orregions centerline 16 which, to facilitate folding of the substrate, may be formed by scoring or perforation. A pair of die-cut openings regions openings FIG. 1 , not all packaging applications requires both openings. The die-cut openings generally approximate the outline of the product being packaged.Substrate 10 is sized to allow approximately a oneinch sealing area 22 along the perimeter of the substrate and surrounding the die cut openings, as suggested bydotted line 24. The width and shape ofsealing area 22 can be varied to suit the size and weight of the product to be packaged. Larger, heavier products typically require a wider sealing area to ensure integrity of the package. - The
thermoformed blister layer 30, shown inFIG. 2 , is produced preferably from recycled polyethylene terepthlate (RPET) resin with a normal thickness of 10-15 millis (0.010-0.015 in). The blister layer is produced in a well known manner by placing RPET film into a forming dye (not shown) under heat and pressure. IN the preferred embodiment, the die closely approximates the shape of the product or products to be packaged and forms regions orvolumes 32 for receiving the product. The blister layer design incorporates aflange 34 disposed generally betweenperimeter 36 of the blister layer andedges 38 ofregions 32. In the preferred embodiment,flange 34 is approximately 0.38 in. wide. The flange serves to contain the blister layer and product(s) within a substrate lamination formed when the corrugate body is folded along line 15 (FIG. 1 ) and sealed as described hereinafter. In those instances when it is desirable that the packaged product be viewable from both sides, a second blister layer (a mirror image of the first) needs to be formed. One blister layer is installed intosubstrate openings 18 and 20 (FIG. 1 ). - The unique properties of the dry tack adhesive are a critical element of the package. The adhesive is a formulated latex rubber product that is applied in aqueous (water-based) liquid form, but which dries as a dry tack adhesive (also referred to as a cohesive) which adheres to itself and the substrate, but not to most other surfaces such as the blister layer. This selective adherence property enables the blister layer to be removed or separated for recycling without adhesive residue or fibrous residue material from the substrate, especially a corrugate substrate, remaining on it. This facilitates efficient recycling of the RPET material. The adhesive properties are carefully controlled to create an environmentally acceptable adhesive with unique cohesive properties that also enable handling and transportation of the coated, unsealed substrates without blocking (i.e. the sticking of substrates to one another).
- In the preferred embodiment, the physical properties of the adhesive are aqueous solution, solids 66% by weight viscosity (dry aged) of approximately 4000 CPS (Centipoise) in 3 months; rheaology—highly pseudo-plastic and thixotropic, with a ratio of viscosity at one RPM (revolution per minute) to viscosity at 50 RPM of approximately 14. : pH—alkaline approximately 10.5 ammonical, viscosity (liquid form)—1330 CPS. The viscosity is controlled at application by thinning with water.
- The adhesive is applied to the substrate using a conventional roll coating machine. In the preferred embodiment, the single bottom roller coating process is utilized.
FIG. 3 shows a typical arrangement.Substrate 10 is positioned for linear movement betweenrollers unprinted substrate surface 42 and is spread uniformly byroller 38, as the substrate advances in the direction indicated byarrow 48. The single bottom roll coating process is used to ensure a uniform coating on theunprinted side 42 of the substrate. Care must be taken to prevent transfer of the cohesive to the printed (finished)side 46 of the substrate. Once the substrate has been coated, it is air dried or heat-dried to produce a tack-free surface. Finished adhesive-coated substrates should be stored in a dry, temperature controlled area maintained at between 40-100 degrees Fahrenheit, and protected from dust and light, especially ultraviolet (UV) light. - Actual packaging of products using the blister pack system is relatively straight forward and typically occurs at a location different from where the substrate coating and blister layer operations occurred. Referring now to
FIGS. 1-4 , theproducts 50 to be packaged and blister layers 30 (assuming the products are to be viewed from both sides) are placed into die-cut openings line 16.Substrate body 10 is folded so that the cohesive-coatedsurface 42 on eachsubstrate region FIG. 4 ) lying generally outsideblister layer perimeter 36 and the outside edges of thesubstrate 10 and holdflange 34 there-between. Once the substrate has been forced to contain the blister layers and products,area 52 must be pressure-sealed to ensure a complete bond between the two substrate surface alongarea 52 to firmly holdflange 34 of the blister layer in place. Adequate pressure is required to develop the bond. This pressure can be produced by the use of a manual or mechanical weighted roller, or other mechanical means (including commercially available card/blister sealing machines), as long as the resulting pressure is sufficient to bond the cohesive, thereby producing a finished laminated package which contains the products and blisters between the substrate, as shown inFIG. 4 . - It will be appreciated that utilization of perimeter sealing of the substrate, as disclosed, results in a tamper-resistant package and enables packaging of heavy products.
- The invention has been disclosed with reference to its preferred embodiment. It will be recognized, however, that variations are possible. For example different types of substrate materials such as corrugate or chipboard may be used. Similarly, substrates of different thicknesses may be used based upon the size and weight of the product to be packaged. Different printing techniques may also be used to create the graphics on the substrate. Different adhesive formulations may be usded instead of the specific cohesive formulation disclosed herein, but the selected adherence properties and ability to handle and ship coated substrates prior to assembly is a critical element of the package.
- The foregoing description of one of the embodiments of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosd. Many modifications and variations are possible in light of the above description, without fundamentally deviating from the essence of the present invention. It is intended that the scope of the invention not be limited by this description.
