RPC Containers Halstead says that by using a single material for the cap and the valve, its latest product will tap growing demand for greater recyclable throughout the industry. Major producers of condiments, like Unilever and Heinz, last week committed to proposals drawn up by the Waste & Resources Action Programme (Wrap). They were designed to cut down on packaging waste going to landfill, which the UK must do if it is to meet EU waste targets. RPC is hoping to meet these industry demands with its new product range. The valve feature, increasingly used in condiment caps to create a "suck back" action to keep the spout clear, is often made of a separate material from the rest of the lid, says the company. To this end, by using a single polypropylene material for both functions, the company says its cap will provide an environmentally viable solution for producers seeking to increase recycling activity. "Consumers appreciate the benefit of the directional spout which enables them to control the delivery of the sauce," RPC stated. "While for manufacturers a single material solution is both more cost-effective and provides a more favourable environmental profile." The company said that along with sustainability, the cap also boasts a number of functions that boost functionality. To prevent leakage whilst the packaging is being stored upside down, the design also includes a plug-in seal that fits into the spout when the cap is closed. The product is also available in two different sizes, one designed specifically for ketchups and sauces, the other for mayonnaise and salad creams. RPC added that it will also release additional versions for relishes at a later date. RPC said that it was looking to expand its portfolio of headstand caps to tailor for increasing demand for the products in the market.
