    What is Polypropylene (PP) ? It is a rigid and crystalline thermoplastic used widely in everyday objects like packaging trays, household products, battery cases, medical devices, etc. Polypropylene is a polymer whose monomer is propylene (an organic hydrocarbon with the chemical formula C3H6). The chemical formula of polypropylene is (C3H6)n. This polymer is also known as polypropene and is often denoted by the abbreviation 'PP'. Generally, polypropylene is produced via a chain-growth polymerization reaction involving propylene. This polymer is known to be a thermoplastic polymer, i.e. it softens upon heating and can, therefore, be remoulded. Its popularity had exploded and widespread commercial production. Today it is one of the most commonly produced plastics in the world. What type of products can it be made into in the blister industry? Most of them are in food industry, why for this? PP material is high temperature resistant and freezable, also it is food grade type. Polypropylene is a material that is fully recyclable. Bacteria, fungi, and other microbes are vulnerable to polypropylene. Polypropylene is a non-toxic material found in nature.

  • Types of Plastic Food Packaging and Safety
    Types of Plastic Food Packaging and Safety
    March 04, 2023
    Types of Plastic Food Packaging and Safety Did you know? Plastic is a surprisingly versatile material with elemental origins. Elements from the periodic table, such as carbon, hydrogen, oxygen, nitrogen and sulfur, are the building blocks for a variety of plastics used to make many of the products we use every day. Some plastics are transparent and durable for use in eyeglasses or safety goggles. Other plastics are strong and lightweight, allowing us to ship more products with less packaging. Plastics can even be bacteria-resistant for use in food packaging and life-saving medical equipment. You don't have to be a scientist to understand the many ways plastics are useful. Plastics are used in many types of food packaging and containers for a variety of reasons – they help protect foods from damage, provides food safety and extends the freshness of foods.   What are the different types of plastics used in food packaging? You may have seen the number 1 through 7 on the bottom or side of a plastic packaging container. This number is the plastic “resin identification code,” also known as the “recycling number.” This number can also provide guidance for consumers who want to recycle plastic containers. Many major types of plastic resins used in packaging (#1 through #7) are recyclable. Most frequently, community recycling programs collect plastic bottles made from PET (#1) and HDPE (#2), but many communities are expanding their programs to collect additional types of plastics. Although most communities instruct residents to recycle by the shape of an item (e.g., bottles, containers, caps, lids), some communities also refer to the resin identification code. If you have questions about which plastics are recycled in your community, see the 2015-2016 Study on Recycling Access and check with your local recycling or solid waste facility. It’s easy to search online.

    Carded Packaging: The Difference Between Blister, Skin And Clamshells(A)
    May 11, 2023
    Carded packaging is a type of packaging which includes three subcategories. Skin, blister, and clamshell packaging supplies are widely used across the world, but what are differences between these three items? From fishing supplies to hardware, from pharmaceuticals to arts and crafts, the applications for these packaging types are virtually endless, but each of them has their own subtle differences and uses. While all in the same class of packaging supplies, clamshell, skin, and blister packaging are each a unique product in and of themselves. Below we will dive into a broad description of each type of carded packaging, discuss their uses and benefits as well as potential downfalls and environmental impacts. Skin Packaging What is skin packaging? Skin packaging (also known as skin packs), is a carded packaging supply that places the product contained within on a piece of paperboard. A slim sheet of see-through plastic which covers the product and paperboard backer is then applied. The paperboard may or may not also have a heat-seal coating. The plastic substrate (LDPE, PVC, ionomer, etc.) is made soft via the use of heat and is then placed over the product on the paperboard backer. Vacuum sealing is occasionally implemented to ensure a tight fit. The substrate then bonds to the heat-seal coating on the paperboard. Skin packaging looks and feels similar to a blister pack, the notable difference being that the plastic covering the product takes the shape of the product, rather than being pre-formed prior to application. Plastic film used in skin packaging includes: Polyethylene PVC Ionomer PET Products commonly sold in skin packaging include fish, pork, chicken, beef, tools, hardware and etc. Virtually any object considered a small consumer product can be packaged in these dynamic packaging supplies. One of the major drawbacks to skin packaging is an experience known as "wrap rage" which is a feeling of extreme annoyance and/or stress from not being able to easily open a product’s packaging and having to utilize scissors or another tool just to remove the packaging from the product. Of the three carded packaging types we are discussing today, skin packs are perhaps the most troublesome products in this respect. On the other hand, clamshells are probably the  easiest type of packaging to open. Clamshells often feature the ability to be easily pulled apart without the need for the intervention of scissors or cutting tools. The reason skin packaging is often chosen in light of the potential frustrations is that they offer a more secure and tight packaging than both blister or clamshells. When being used for food applications such as the packaging of fish, beef, pork or chicken, they are superior in the protection of the product and the prevention of contamination as they are vacuum sealed and the product contained within is devoid of oxygen.

While there are countless ways to package your product, here are the top 5 advantages that blister packaging has to offer. 1. High-quality product protection without compromising experience - The heat seal coating on blister packaging protects your product from any element that would otherwise damage the product & thereby maintain its integrity. Whether the packaging is for food, medical products, or anything with an expiration date; you can trust that your packaging will deliver on the quality that you promise. 2. Diverse marketing options - Landsberg uses the industry’s first 7-color processor to print vibrant colors giving you unlimited design options. This world-class processor has the power to match & print every company's unique color palette with a vibrancy that has not been possible until now. 3. Engagement for the consumer - Blister packaging provides a unique opportunity for consumer engagement. With a clear plastic cavity around the product, consumers are able to view & sometimes even touch the product without compromising or contaminating the product before purchase. The potential to interact with a product before a purchase can make all of the difference. 4. Secured Value - While consumers are able to engage with the products, blister packaging by design is tamper-resistant & deters theft.  5. Cost-Effectiveness - Blister packaging saves you money since it requires fewer tooling costs & is easier to produce than some other packaging methods.

    Can distinctive packaging also give a boost to products sold to businesses and institutions?

    Double-Blister Package Sets Surgical Device Apart Manufacturers often use packaging to differentiate consumer products vying for attention on store shelves. But can distinctive packaging also give a boost to products sold to businesses and institutions? This was the question posed by executives at Remington Medical Inc., a supplier of cardiovascular medical devices. Remington decided to give its vascular introducer set, which is used to implant pacemakers in hearts, a new double-blister package that's easier to handle and provides more assurance that sterility will be maintained in the operating room than the original single-blister package. The Alpharetta, GA, company is the first supplier of vascular introducers to use a double-blister style. The complete double-blister package designed by Blue Ridge Packaging includes an inner package (shown sealed) and an outer tray (with the Tyvek lid pulled back). The new package, designed and made by Blue Ridge Packaging of Simpsonville, SC, includes inner and outer trays. The inner thermoformed tray, made of 25-mil clear vinyl Pentamed MD 557-00-16200 from Klöckner Pentaplast of America (Gordonsville, VA), includes compartments for each of the elements of the introducer set (dilator, sheath, guidewire, needle, and syringe) and is sealed with a Tyvek lid. The outside rectangular vinyl tray is also thermoformed and sealed with Tyvek. After the inner tray is sealed in the outer tray, the package is EtO-sterilized.

Blister packaging keeps supplements sealed and inhibits tampering, providing better sanitation and quality control.  The guide below will explain what materials are used in blister packaging. What Is Blister Packaging? Blister packaging is widely used across the pharmaceutical industry as a unit-dose packaging solution that helps people take the correct amount of medication at the right time.  Blister packaging is made using several types of rugged polymers, including: Polyethylene terephthalate (PET) Polyvinyl chloride (PVC) Polyvinylidene terephthalate glycol (PETG) Polystyrene (Ps) Polypropylene (PP) Blister packaging is manufactured from a plastic sheet that is thermoformed to create cups or blisters that hold a product in place. The packaging typically has a paperboard backing or a lidding seal of aluminum foil or plastic film. Blister Packaging Properties Blister packs provide a safe, secure way to ship medicines and small consumer items, offering additional protection when goods are transported inside custom cardboard boxes.
