7 common mistakes when specifying industrial plastic caps

During my more than two decades working in the industrial sector, I have realized how much the choice and specification of plastic caps can affect the success of a product. With the solutions offered by Bral-Max standing out in the market, it has become even clearer to me that small mistakes in the choice or design of lids can lead to losses and delays. That's why I want to share the 7 most common mistakes I've seen happen over the years, so that your company can avoid headaches and optimize its results.

1. Disregard the chemical compatibility of the material

A common mistake is to believe that any plastic will work for any product. I've witnessed cases where satin lids, for example, have reacted with certain chemical formulations, causing everything from deformations to leaks. It is essential to ensure that the lid material is suitable for the product being filled. Materials such as PP, PE and PET have different characteristics and respond in different ways to solvents, oils and acids. Uma simples consulta técnica pode evitar sérios contratempos, prejuízos financeiros e até riscos à saúde do consumidor final.

2. Ignoring closure variables

I've seen companies that, by prioritizing only the look or cost, end up neglecting the type of closure. The result? Complaints of leaks, difficulty in use or the lid breaking.

• Threadable closure
• Flip-top
• Snap-on (pressure)
• Safelock

Each type of closure offers different levels of sealing and practicality. And at Bral-Max, for example, there are specific lines for each application, precisely with these details in mind. Checking with the manufacturer is the first step to avoiding problems with the product's fit or poor sealing.

Designing the right type of lock is half the battle for safety.

3. Failure to consider standards and legislation

This is a point I often reinforce with everyone who takes part in industrial projects with me. The packaging sector is regulated by various standards, especially in the food, pharmaceutical and cosmetics segments. Specifying lids without respecting Anvisa, Inmetro or international standards can lead to whole batches being rejected, fines and recalls. Always consult serious suppliers - as I do with Bral-Max - and keep up to date with the legislation for each segment.

4. Stick to the standard without looking into customization

Muitos projetos começam com a busca por tampas iguais às usadas por outros produtos do setor, mas se esquecem que a personalização é uma ferramenta de diferenciação na prateleira. Em meus acompanhamentos no varejo, noto como pequenas alterações em cor, textura e formato podem chamar a atenção e agregar valor à embalagem. Vale a pena discutir sobre customização, ampliações ou adaptações da tampa. No portfólio da Bral-Max, há uma ampla cartela de cores e opções de design flexíveis. Não se esqueça de alinhar também os volumes mínimos e prazos com o fabricante.

5. Underestimating the impact of logistics

Nem sempre vejo as equipes técnicas considerando as condições de transporte e armazenagem na especificação das tampas. Já presenciei situações em que um ótimo protótipo simplesmente não suportou o transporte em caminhões sob calor intenso ou empilhamento no estoque, causando deformações ou perdas de produto. Ao especificar, analise junto ao fornecedor como a tampa se comporta em diferentes ambientes e temperaturas. Leve em conta:

• Need for stacking
• Impact resistance
• Exposure to sunlight

These details can be decisive in avoiding losses during distribution.

6. Forgetting the end user experience

Another common slip-up is to focus only on technical performance and end up forgetting about the consumer. It's essential to think about caps that are easy to open, close, dose and handle, especially in the hygiene, cosmetics and food sectors.

Packaging is often the customer's first contact with your brand.

I once worked on a project that had to be revised because consumers were finding it difficult to open the lid. A simple consultation of usability tests, as we do by default at major manufacturers, could have avoided rework and extra costs.

7. Not planning for future innovations or trends

The market is dynamic and requires constant updating. I see brilliant projects fail precisely because they ignore the need to adapt caps to new formats, antimicrobial technologies or sustainable practices. Sustainability, for example, is no longer a differential and has become a requirement in many contracts. Planning with trends, circular economy and environmental responsibility in mind makes all the difference to a product's longevity. That’s why modern projects are designed from the outset to be easily recyclable and have a smaller carbon footprint. In fact, it’s worth checking out an article that delves deeper into sustainable innovation in this sector.
