A Comprehensive Guide to Choosing Blister Pack Printing Adhesives that Meet Regulatory Standards

3 · 01 · 23

Blister packing plays a crucial role in the packaging of various products such as pharmaceuticals, food, and cosmetics. Packaging design and print are crucial aspects that manufacturers and consumers alike pay great attention to. To ensure the quality of the blister pack, manufacturers work closely with printing adhesive partners to ensure that high-quality packaging materials are used for all components, including adhesives, printing ink, and substrates.

Breaking the Seal on Blister Pack Printing Adhesives: Unveiling the Importance of High-Quality Materials

Ensuring the safety of products meant for human consumption is a vital responsibility for regulatory agencies. Guidelines for packaging and storage play a crucial role in achieving this goal. There are certain areas where consumer safety might be compromised, such as:

  • Food products where the packaging can come into contact with the food
  • Medication where the adhesive used in the packaging could seep into the product
  • Inks that may react with the medical product, compromising its effectiveness
  • Additionally, certain materials used in packaging, such as rubber containing latex, can trigger severe allergic reactions. It’s essential to be aware of the potential risks and take necessary precautions to ensure the safety of the products we use

The Building Blocks of Success: Exploring the Impact of High-Quality Materials in Manufacturing

Regulatory agencies place the highest priority on ensuring the safety of food packaging. Plastics that come into contact with food are subject to stringent safety regulations, and a list of approved substances is available. 

Printers are often required to provide comprehensive ingredient lists for various categories of materials used in production. These can include: 

  • Inks
  • Rubbers
  • Substrates

By understanding the composition of these materials, printers can ensure that their products meet safety regulations and promote consumer well-being. These measures also help to build trust with consumers, who are increasingly concerned with the safety and transparency of the products they use.

When it comes to pharmaceutical packaging, there are several industry guidelines and regulatory requirements that must be followed to ensure the safety and efficacy of the medication. These guidelines cover a range of topics, from the materials used in packaging to the design of blister packs and other delivery systems. 

By adhering to these standards, pharmaceutical companies can ensure that their products are safe, effective, and compliant with industry best practices. This is critical for maintaining consumer trust and promoting better health outcomes. Some of these guidelines are:

  • Pharmaceutical packaging should be designed to be appropriate for the dosage and the method of administration, and made from materials that are safe for this purpose.
  • Blister packaging used for medications should not allow harmful or undesirable substances to leach into the medication during treatment.
  • Packaging materials used for pharmaceutical products should not have any negative effects on the quality of the dosage.
  • The chemical composition of packaging materials can affect their compatibility, function, and protective properties. This may change factors such as elasticity, resistance to solvents, or gas permeability.
  • If the packaging is not adequately sealed, there is a risk of contamination by ink or adhesive components.
Blister packing has become a popular choice for protecting medication due to its tamper-evident properties and ability to maintain the quality of the medication. It is essential to ensure the safety of all materials involved in the packaging process, including packaging, adhesives, and printing ink that meet safety standards. This helps to preserve the integrity of the medication, ensuring it remains safe and effective for patients.

Preserving Integrity: The Vital Importance of Understanding Compliance Responsibilities in Blister Pack Printing

Although most of the responsibility falls on the product manufacturer’s side, it’s crucial to find a printing partner that prioritizes safety and compliance. Ensure that the printer you work with uses materials and processes that adhere to established safety standards. 

If the blister pack printing adhesive fails to perform its job properly or harms a consumer, the company could face consequences. Some of the consequences could be:

  • Recalls
  • Lawsuits
  • Negative publicity

To ensure that all materials and processes used in the production meet safety standards, a printer may need to request documentation from all vendors in the production line. It’s important to allocate sufficient time in the production process to obtain these assurances. When introducing new products, additional testing time should be taken into account to ensure compliance with safety standards.

Beyond the Checklist: Navigating the Complexities of a Compliant Printing Process

Verifying that all components used in blister pack printing adhere to safety standards is crucial for the integrity of the protected medication. The printer should ensure that image carriers used are compliant with regulatory guidelines, in addition to inks and adhesives. 

Image carriers that transfer ink and adhesive safely and effectively can be sourced, including those that are latex-free. If you have questions about regulatory issues or other concerns regarding blister packing, consider consulting with an expert in flexographic printing.
